摘要

摘要: 城市建筑安全涉及人民的生命财产,近年已有多起建筑局部坍塌造成严重损害。为实现"灾前预防"的现代化城市建筑设施安全监管,基于PS-InSAR技术,提出一种针对于城市建筑及基础设施的大范围安全风险评估方法。通过结合InSAR原理,提取建筑PS点聚类,分析聚类点形变信息,根据建筑物风险相关指标提取有效形变,参考建筑类型及区域情况划分风险等级标准,进而评价区域内建筑设施的安全风险情况。以长春市为例,利用COSMO-SkyMed卫星时序数据,对主城区建筑物进行大范围安全风险监测试验,并对评价为D级需重点关注的建筑进行实地踏勘,发现均存在较为明显的隐患情况。证实了方法的可行性以及准确性,能够为大范围城市建筑设施定期"体检"提供技术支持,保障城市建筑安全。

Abstract: The safety of urban buildings involves people’s lives and property. In recent years, there have been many local collapses of buildings causing serious damage. In order to realize the "pre-disaster prevention" safety supervision of modern urban building facilities, a large-scale safety risk assessment method for urban buildings and infrastructure was proposed based on PS-InSAR technology. By combining InSAR principle, the building PS point clustering was extracted, the deformation information of cluster points was analyzed, the effective deformation was extracted according to building risk related indicators, and risk grade standards were divided according to building types and regional conditions, so as to evaluate the safety risk situation of building facilities in the region. Taking Changchun City as an example, using the COSMO-SkyMed satellite time series data, a large-scale safety risk monitoring experiment was conducted on buildings in the main urban area, and a field survey was conducted on buildings that were evaluated as grade D and needed to be paid attention to, and it was found that there were obvious hidden dangers. The feasibility and accuracy of the method were confirmed, and it could provide technical supports for regular "physical examination" of large-scale urban building facilities and ensure the safety of urban buildings.
