Risk Assessment of Foundations in Karst Terrain

9612675这项风险评估研究是一项初步研究，将为易受天坑形成影响的地点的地基发展一套系统的风险评估方法。这一方法将结合表征、准备和设计来评估在岩溶地形上建造的建筑物(例如，建筑物、高速公路和挡土墙)的风险。在文献回顾之后，将对风险评估的标准方法进行评估，以确定哪种方法或混合方法最适合进行系统方法分析。这项研究将包括最近因天坑造成的结构损坏和/或坍塌的案例研究，并评估目前用于确定岩溶地区场地和设计基础的方法的局限性。***

9612675 This RPG research is a preliminary study which will lead to development of a systematic approach to risk assessment for foundations at sites that are susceptible to sinkhole formation. This approach will combine characterization, preparation and design to assess risk of structures (e.g., buildings, highways, and retaining walls) built on karst terrain. Following a literature review, standard approaches to risk assessment will be evaluated to determine which approach or hybrid of approaches would be best suited to a systems approach analysis. The study will include recent case studies of structure damage and/or collapse due to sinkholes, and assess the limitations in current methods used to characterize sites and design foundations in karst areas. ***
