摘要

目的强降雨是造成历史夯筑物退化的主要原因之一。因此,确保其保护需要了解这些风险情况中涉及的因素。本研究的目的是研究过去三次降雨对安达卢西亚历史悠久的夯土防御工事造成破坏和坍塌的事件,以分析是否有可能防止类似情况在未来发生。设计/方法/方法分析的三个案例研究位于西班牙南部,发生在2017年至2021年之间。在这种情况下,降雨带来的危害已从Art Risk 3.0(注册号201999906530090)获得。结构的脆弱性已经用艺术风险1模型进行了评估。为了表征降水事件的强度、持续时间和强度,设计、验证和测试了GPM和GSMaP卫星资源的统计使用工作流程。根据地面气象站的数据对风力进行了评估。FindingsGSMaP降水数据与地面气象站的数据非常相似。关于所分析的三个风险事件,尽管它们发生在有暴雨危险的地区,但破坏是由不超过5毫米/小时的非强降雨造成的。降雨持续了几天,墙壁保护状况不佳,似乎是引发坍塌的因素,从根本上影响了修复砂浆。独创性/价值提出了一种应用于脆弱性和危害分析的工作流程,该工作流程验证了大规模使用卫星图像来监测过去和现在因降雨而造成的遗产结构风险情况。

Remote sensing to assess the risk for cultural heritage: forecasting potential collapses due to rainfall in historic fortifications
PurposeHeavy rainfall is one of the main causes of the degradation of historic rammed Earth architecture. For this reason, ensuring the conservation thereof entails understanding the factors involved in these risk situations. The purpose of this study is to research three past events in which rainfall caused damage and collapse to historic rammed Earth fortifications in Andalusia in order to analyse whether it is possible to prevent similar situations from occurring in the future.Design/methodology/approachThe three case studies analysed are located in the south of Spain and occurred between 2017 and 2021. The hazard presented by rainfall within this context has been obtained from Art-Risk 3.0 (Registration No. 201999906530090). The vulnerability of the structures has been assessed with the Art-Risk 1 model. To characterise the strength, duration, and intensity of precipitation events, a workflow for the statistical use of GPM and GSMaP satellite resources has been designed, validated, and tested. The strength of the winds has been evaluated from data from ground-based weather stations.FindingsGSMaP precipitation data is very similar to data from ground-based weather stations. Regarding the three risk events analysed, although they occurred in areas with a torrential rainfall hazard, the damage was caused by non-intense rainfall that did not exceed 5 mm/hour. The continuation of the rainfall for several days and the poor state of conservation of the walls seem to be the factors that triggered the collapses that fundamentally affected the restoration mortars.Originality/valueA workflow applied to vulnerability and hazard analysis is presented, which validates the large-scale use of satellite images for past and present monitoring of heritage structure risk situations due to rain.

期刊介绍: The International Journal of Building Pathology and Adaptation publishes findings on contemporary and original research towards sustaining, maintaining and managing existing buildings. The journal provides an interdisciplinary approach to the study of buildings, their performance and adaptation in order to develop appropriate technical and management solutions. This requires an holistic understanding of the complex interactions between the materials, components, occupants, design and environment, demanding the application and development of methodologies for diagnosis, prognosis and treatment in this multidisciplinary area. With rapid technological developments, a changing climate and more extreme weather, coupled with developing societal demands, the challenges to the professions responsible are complex and varied; solutions need to be rigorously researched and tested to navigate the dynamic context in which today''s buildings are to be sustained. Within this context, the scope and coverage of the journal incorporates the following indicative topics: • Behavioural and human responses • Building defects and prognosis • Building adaptation and retrofit • Building conservation and restoration • Building Information Modelling (BIM) • Building and planning regulations and legislation • Building technology • Conflict avoidance, management and disputes resolution • Digital information and communication technologies • Education and training • Environmental performance • Energy management • Health, safety and welfare issues • Healthy enclosures • Innovations and innovative technologies • Law and practice of dilapidation • Maintenance and refurbishment • Materials testing • Policy formulation and development • Project management • Resilience • Structural considerations • Surveying methodologies and techniques • Sustainability and climate change • Valuation and financial investment
