Recently, Ministry of Land, Infrastructure and Transport has amended the law to Design for Safety in working design stage of construction work. There should be informed the disaster likelihood and severity of unit-works to decide risk of unit-works in Design for Safety. Therefore, the construction disaster data of OO corporation were classified as 24 unit-works and the disaster likelihood and severity of unit works were analyzed in this study. The safety management level of unit-works which based on analysis data was suggested 3 groups; special management and emphasis management, regular management. The results of this study can be used as basic information to perform Design for Safety in construction. And this information will be able to reduce the disaster.
最近,国土交通部修改了《建筑工程施工设计阶段安全设计法》。在安全设计中,应了解机组发生灾害的可能性和严重程度,以确定机组的风险。因此,本研究将OO公司的施工灾害数据分类为24个单体工程,并对单体工程的灾害可能性和严重程度进行分析。根据分析数据,提出了机组安全管理水平分为3组;专项管理、重点管理、常态化管理。研究结果可作为施工安全设计的基础资料。这些信息将能够减少灾难。

Overseas Urban Development is even risky although it is desirable for market-seeking developed countries and developing countries facing urbanization problems. Both sides do not know each other well so that they cannot trust each other to work on this risky projects. This study constructs a frame, which is enhancing trust between developed and developing countries. The first step is to start from small collaborations than a huge project. At the charismatic position, a enterprise from developed country proceeds its first work with its most advanced skills, cooperating with developing countries. By localization with executing projects smaller and easier than urban development project, like constructing facility or buildings, this enterprise can get closer to native elites and get to be supported from native people. And then, they can start huge urban development project. The study begins with trust theory, adding case studies contributing to constructing Cooperative Overseas Urban Development Frame. Five cases were studied and applied by the international urban development framework.
对于追求市场的发达国家和面临城市化问题的发展中国家来说,海外城市发展是有风险的。双方都不太了解对方,所以他们不能信任对方去做这个有风险的项目。本研究构建了一个框架,即增强发达国家与发展中国家之间的信任。第一步是从小型合作开始,而不是一个大项目。在魅力地位上,一个来自发达国家的企业以其最先进的技术与发展中国家合作进行其第一次工作。通过本地化,实施比城市开发项目更小、更容易的项目,比如建造设施或建筑物,企业可以更接近当地的精英,得到当地人的支持。然后,他们可以开始大规模的城市发展项目。本研究以信任理论为出发点,加入个案研究,建构合作海外城市发展框架。国际城市发展框架研究并应用了五个案例。

This study aims to find implications for urban economic regeneration strategies of local initiative by analyzing of promoting regional strategic industries, both Seongnam and Goyang in terms of regional industrial policy, institution and specialized service agency. The main results based on the case studies are as follows. First, It is a top priority to formulate the policy direction, such as selecting strategic industries and prepare means for improving it. It should keep reliability and continuity for inducing economic units. Second, It is necessary to consider the effectiveness and diversity of institutions. The institutions to be formalized by municipal ordinance and rules for making the successful implementing system of policies. It is necessary to implement strategic industry policy linked with the central government or public organizations for expanding of a diversity of policies. It is necessary to change in viewpoint on the deregulation and tax break for the private sectors as inducements to achieve the regional economy activation. Third, It is necessary to introduce the specialized service agency to improve an effectiveness and efficiency of institutions and accelerate a network within economic units.
本研究旨在从区域产业政策、制度和专门服务机构三个方面,分析城南和高阳市促进区域战略性产业的情况,找出地方主动性城市经济再生战略的启示。基于案例研究的主要结果如下:首先,制定政策方向是当务之急,比如选择战略性产业,并准备完善的手段。它应保持可靠性和连续性,以吸引经济单位。第二,要考虑制度的有效性和多样性。为制定政策的成功实施体系,需由市政条例和规章确定的机构。为了扩大政策的多样性,有必要实施与中央政府或公共机构相联系的战略性产业政策。为了激活地区经济,有必要改变对民间企业放宽限制和减税的看法。第三,要引入专门的服务机构,提高机构效能和效率,加快经济单位内部的网络化。

Economic Self-Sufficiency Criteria for New Town Planning by Network Characteristics 基于网络特征的新城规划经济自给标准
Pub Date : 2016-10-31 DOI: 10.5804/LHIJ.2016.7.4.251
Young-Il Song, Joo-Ho Rhim
As the spatial structure of a region is evolving into a decentralized multi-nucli model, networked connection among cities in a region is emerging as an important issue to strengthen regional competitiveness. This paper focused on the limitation of current new town planning criteria which just suggest a uniform standard for economic self-sufficiency by new-town size, without representing the network characteristics of new town. If a new town is planned as a economic strongpoint within a region, it needs to secure appropriate industrial functions. This study classified the characteristics of new towns by network analysis and reviewed the economic self-sufficiency criteria by new town types. Using various network connectedness indices, the 1st and 2nd round new towns in the capital region were analyzed, and land-use distribution of new-towns in other countries were also examined comparatively. The network characteristics of new towns are classified as three types: mono-nucleus, distributed center, and dependent. Based on this classification, planning criteria for self-sufficiency were compared among 6 new towns. This study provides implications for the amendment of "the sustainable new town planning criteria" or the revision of development plans.
随着区域空间结构向分散的多核模式发展,区域内城市之间的网络化连接成为增强区域竞争力的重要问题。本文针对现有新城规划标准的局限性,提出了以新城规模作为经济自给自足的统一标准,未能体现新城的网络化特征。如果把新城市规划为地区内的经济据点,就需要确保相应的产业功能。本文运用网络分析法对新市镇特征进行了分类,并对新市镇类型的经济自给标准进行了梳理。利用各种网络连通性指标,对首都圈第一轮和第二轮新城进行了分析,并对其他国家新城的土地利用分布进行了比较。新型城镇的网络特征可分为单核型、分布式中心型和依赖型三种。在此基础上,对6个新镇的自给自足规划标准进行了比较。这项研究对修订“可持续新市镇规划准则”或修订发展图则有影响。

Behavior of Lateral Earth Pressure around the Underpass Constructed by the STS Construction Method STS法地下通道周边侧土压力特性研究

Recently developed trenchless construction methods ensure stability for the ground settlement by inserting steel pipes along the underpass section and integrating steel pipes before ground excavation to form pipe-roof. This study is to confirm the reinforcing effect of pipe-roof by measuring lateral earth pressure acting on the underpass constructed by the STS (Steel Tube Slab) construction method. For this purpose, lateral earth pressure was measured at the left and right side of the pipe-roof after installing earth pressure cells. As a result, lateral earth pressure was measured with considerable reduction because the integrated pipe-roof shared surcharge. Therefore, economic design for the underpass could be expected by sharing design load by pipe-roof. In addition, construction cost was analyzed according to the design-load sharing ratio by pipe-roof. As pipe-roof shares design load by 40%, the total construction cost can decrease by almost 10% in the case of four-lane underpass.
近年来发展起来的非开挖施工方法是在地下通道段插入钢管,在地面开挖前将钢管连成管顶,以保证地面沉降的稳定性。本研究是通过测量钢管板(STS)施工法下穿隧道的侧土压力,来确认管顶加固效果。为此,在安装土压力箱后,分别在管顶左右两侧测量侧土压力。结果表明,由于一体化管顶共压,侧土压力测量值显著降低。因此,通过管顶分担设计荷载,可以实现地下通道的经济设计。此外,根据管顶设计荷载分担比,对施工成本进行了分析。在四车道地下通道的情况下,由于管顶分担设计荷载的40%,总施工成本可以降低近10%。

There are small box opening for inserting of electric lamp box in the slab of apartment. Around this box opening, we normally use the detailing of WWF or plastic ring strengthening to protect cracks induced by shrinkage. The shrinkage amount of slab box around was measured and analysed in order to consider validity of these strengthening methods and to find out economical alternative. Alternative of strengthening methods are normally used strengthening methods in construction companies, which are WWF strengthening, plastic ring strengthening and no strengthening methods. The shrinkage amount was measured using contact guage at the spot of tip attached around the box on slab of small area unit apartment which have small exclusive area below 59 ㎡ . Measured data shows that there are no big differences between all the 3 strengthening methods and Measure data range is -264 με ~ +216 με . Measured shrinkage is on trend slightly increase till 3~5weeks after removal of forms and then decrease. But amount of shrinkage are very low for all the slabs and there are no probabilities of concrete crack by shrinkage.
公寓楼板上有插电灯箱的小箱口。在此箱口周围,我们通常使用WWF或塑料环加固的细节来保护收缩引起的裂缝。对板坯箱周围的收缩量进行了测量和分析,以考虑这些加固方法的有效性,寻找经济可行的替代方案。施工企业常用的加固方法有:WWF加固、塑料环加固和无加固。采用接触计对专用面积小于59㎡的小面积单户制公寓楼板箱体周围贴尖处的收缩量进行了测量。实测数据表明,3种强化方法之间差异不大,测量数据范围为-264 με ~ +216 με。在去模后3~5周,收缩率有小幅上升的趋势,然后下降。但所有楼板的收缩量都很低,不存在混凝土收缩开裂的可能性。
