Qiang Wu, Jiayu Li, Xiaoyan Ding, Li Wang, Nasen Li
Compared with ordinary buildings, Old industrial buildings have short construction period; Lack of policies, regulations and technical standards. In order to ensure the successful implementation of the old industrial building recycling project, all participants must share the project risks reasonably. This paper takes the project of old industrial building recycling as the research object. Firstly, the Delphi method is adopted to identify the project risk. Based on the incomplete contract theory, the risk is clearly divided into the contracting stage and the risk of the performance stage. Secondly, based on participant satisfaction, build index system of risk sharing, using C-OWA operator for risk sharing weighting, avoid the ill effects of the expert subjective preferences, under TOPSIS and UT theory, form a sharing mode that is complete, reasonably define the responsibility attribution of risks and determine the optimal sharing proportion of Shared risks. Finally, the model is applied to a creative industrial park project transformed from a steel mill in Shanxi province to prove the rationality of the model, and provide reference for the formulation of risk sharing scheme of China's old industrial building recycling project. Keywords—old industrial building; recycling; creative industry park;risk sharing 摘要—旧工业建筑再生利用后与普通建筑物相比,具有建设周 期短,缺乏政策法规及技术标准等特点。为保证旧工业建筑再 生利用项目成功实施,各参与方必须合理分担项目风险。本文 以旧工业建筑再生利用为创意产业园的项目为研究对象,首先 采用 Delphi 法识别项目风险,依据不完全契约理论,将风险 明确划分为缔约阶段风险与履约阶段风险;其次构建基于参与 方满意度的风险分担指标体系,利用 C-OWA 算子对风险分担指 标赋权,避免专家主观偏好带来的不良影响,在此前提下将理 想解法(TOPSIS)与效用理论(UT)相结合,形成一套具有两者优 势及完整的风险分担模型,合理界定风险的责任归属和确定共 担风险的最优分担比例;最后将模型应用到由陕西某钢厂改造 而成的创意产业园项目,证明该模型的合理性,为我国旧工业 建筑再生利用项目风险分担方案制定提供参考。 关键词-旧工业建筑, 再生利用, 创意产业园, 风险分担
与普通建筑相比,老工业建筑施工周期短;缺乏政策、法规和技术标准。为了保证旧工业建筑回收项目的顺利实施,各参与方必须合理分担项目风险。本文以老工业建筑回收项目为研究对象。首先,采用德尔菲法对项目风险进行识别。根据不完全合同理论,将风险明确分为合同阶段和履约阶段风险。其次,基于参与者满意度,构建风险分担指标体系,使用C-OWA算子进行风险分担权重,避免专家主观偏好的不良影响,在TOPSIS和UT理论下,形成完整的分担模式,合理界定风险的责任归属,确定共享风险的最优分担比例。最后,将该模型应用于山西某钢厂改造的创意产业园项目,验证了模型的合理性,为中国老工业建筑回收项目风险分担方案的制定提供参考。关键词:老工业建筑;回收;创意产业园区;风险分担摘要——旧工业建筑再生利用后与普通建筑物相比,具有建设周期短,缺乏政策法规及技术标准等特点。为保证旧工业建筑再 生利用项目成功实施,各参与方必须合理分担项目风险。本文以旧工业建筑再生利用为创意产业园的项目为研究对象,首先采用德尔菲法识别项目风险,依据不完全契约理论,将风险明确划分为缔约阶段风险与履约阶段风险;其次构建基于参与方满意度的风险分担指标体系,利用C-OWA算子对风险分担指标赋权,避免专家主观偏好带来的不良影响,在此前提下将理想解法(TOPSIS)与效用理论(UT)相结合,形成一套具有两者优势及完整的风险分担模型,合理界定风险的责任归属和确定共担风险的最优分担比例;最后将模型应用到由陕西某钢厂改造而成的创意产业园项目,证明该模型的合理性,为我国旧工业建筑再生利用项目风险分担方案制定提供参考。关键词-旧工业建筑, 再生利用, 创意产业园, 风险分担

Study on Seismicity and Secondary Disaster Countermeasures of Offshore Earthquake of China 中国近海地震活动性及次生灾害对策研究
Changlong Li
According to statistics, there have been about 420 earthquakes with M6 or higher in China's coastal and offshore areas since the record, including 63 earthquakes with M7 or higher and 3 earthquakes of M8 and above, showing high major earthquake seismicity. At the same time, due to the economic growth of China in recent years, the population, infrastructure and major projects in the coastal areas have increased rapidly. Therefore, it is of great significance to study the dangers of large earthquakes in China's offshore and disaster risk countermeasures. In this paper, we use the data of the fifth generation of China Seismic Hazard Map to calculate the frequency of earthquakes in the offshore areas of China and the offshore areas above the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, and give the major disaster risk countermeasures in the coastal and offshore areas. This paper shows that the frequency of earthquakes larger than M6 in the offshore areas of the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and the whole region is about 0.036, 0.054, 1.03, 0.28 and 1.4 times per year respectively, and the frequency of earthquakes above M7 is about 0.014, 0.021, 0.46, 0.14 and 0.68 time per year respectively. The potential risks of land liquefaction must be guarded in the coastal and estuary delta areas. The potential risks of offshore wave storm, tsunami and land sinking must be guarded in the coastal areas of Fujian, Taiwan, Guangdong and northern Hainan.
据统计,自有记录以来,中国沿海及近海地区共发生M6及以上地震约420次,其中7级及以上地震63次,8级及以上地震3次,具有较高的大地震活动性。同时,由于近年来中国经济的增长,沿海地区的人口、基础设施和重大工程迅速增加。因此,研究中国近海大地震的危险性及灾害风险对策具有重要意义。本文利用第五代中国地震危险度图的数据,计算了中国近海及渤海、黄海、东海和南海近海的地震频率,并给出了沿海和近海地区的主要灾害风险对策。结果表明,渤海、黄海、东海、南海及全海域近海6级以上地震频次分别为每年0.036、0.054、1.03、0.28和1.4次,7级以上地震频次分别为每年0.014、0.021、0.46、0.14和0.68次。在沿海和河口三角洲地区,必须警惕土地液化的潜在风险。在福建、台湾、广东和海南北部沿海地区,必须警惕潜在的近海风暴、海啸和陆地下沉风险。

This earthquake killed 17 people and injured 285 people. The earthquake also caused huge property losses. Most of the casualties of the earthquake were caused by the collapse and damage of the buildings. The near field strong ground motion was the direct reason which caused the collapse of the building. The collapse of the buildings was greatly related to the amplitude and frequency of circulation of ground motion. The seismic response of system accumulated damage under cyclic load depends not only on the maximum amplitude of motion but also on the duration of motion. Many researchers suggest that the effective number of ground motion cycles is more reflective of seismic damage than the duration. The destructive ability of seismic ground motion depends on the amplitude of the movement and the number of cycles. In the geotechnical earthquake engineering, the number of motion cycles is the most important. Many researchers believe that the number of motion cycles is also an important factor in structural seismic design and damage assessment. Because the strength, stiffness and energy dissipation of the structure decreases with the increase of the load cycle, the amplitude itself is not sufficient to evaluate the seismic performance of the structure.

Preliminary Study on Basin Amplification Effect for Vertical Incidence of Two Kinds SH Pulse Waves 两种SH脉冲波垂直入射的盆地放大效应初步研究
Xueliang Chen, Jianlong Wang, M. Gao
Study of basin effect has important reference significance for future urban the planning of earthquake prevention and disaster reduction. The amplification effects of three ideal simple basin models, “square” shape, “inverted convex” shape and “curved” shape, were studied by using the finite element numerical simulation method of decoupled nearfield wave combined with transmission boundary. The results show that: 1. Two kinds of basin models, “square” and “inverted convex”, show different rules of seismic response of basin position along with the depth of basin: the square basin model shows similar characteristics to the existing site response, while the calculation results of inverted convex basin model are more fit our existing basin knowledge. Therefore, it is not appropriate to study the amplification effect of basin earthquake ground motion only by using simple “square” basin model. 2. The seismic response of a more realistic "curved-edge" basin model is studied. The calculation results of the symmetric model show good regularity. A relatively large seismic response occurs in the center of the basin, which reflects the role of the “focusing effect” of the basin. The asymmetric basin model is located in the center of the basin and at the edge of the basin. Greater ground motion responses have been observed on both sides of the basin, even on the steeper edge of the basin, which is related to the “edge effect” of the basin; with the softening of the medium in the basin, the ground motion responses of the site in the basin gradually increase; with the increase of the stratification of the medium in the basin, the ground motion responses of the basin are larger. On the whole, the seismic response also tends to increase gradually, but there are also large differences in some locations of the basin, which reflects the complexity of the amplification effect of the seismic basin.

Greater ground motion responses have been observed on both sides of the basin, even on the steeper edge of the basin, which is related to the “edge effect” of the basin; with the softening of the medium in the basin, the ground motion responses of the site in the basin gradually increase; with the increase of the stratification of the medium in the basin, the ground motion responses of the basin are larger. On the whole, the seismic response also tends to increase gradually, but there are also large differences in some locations of the basin, which reflects the complexity of the amplification effect of the seismic basin.

—From the point of view of the demand of public security application for video information application, this paper compares the characteristics of traditional video surveillance system with that of urban public security video surveillance system, analyses the factors affecting the effectiveness evaluation of video surveillance system, and puts forward the evaluation index set for evaluating video information collection. On this basis, this paper establishes a risk entropy model of public security video surveillance system, and divides the risk of application of video surveillance system into the risk related to fixed target, the risk related to moving target and the risk related to image information quality satisfaction. Among them, the risk related to the moving target can be further divided into the self-risk of the target and the coupling risk between the goals, which are often related to the occurrence of the case or event. The risk entropy model of video surveillance proposed in this paper can be used to evaluate the application efficiency of video surveillance system and guide the layout of video surveillance system in a region.
-从公安应用对视频信息应用的需求出发,比较了传统视频监控系统与城市公安视频监控系统的特点,分析了影响视频监控系统有效性评价的因素,提出了评价视频信息采集的评价指标集。在此基础上,本文建立了公安视频监控系统的风险熵模型,将视频监控系统应用的风险分为与固定目标相关的风险、与移动目标相关的风险和与图像信息质量满意度相关的风险。其中,与移动目标相关的风险又可进一步分为目标自身风险和目标之间的耦合风险,往往与案件或事件的发生有关。本文提出的视频监控风险熵模型可用于评价视频监控系统的应用效率,指导区域内视频监控系统的布局。
