Risk Assessment of Foundations in Karst Terrain

9612675本RPG研究是一项初步研究，将有助发展一套系统的方法，以评估易受天坑影响地点的地基的风险。这种方法将结合特征、准备和设计来评估喀斯特地形上的结构（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，以确定哪种方法或方法的混合最适合系统方法分析。该研究将包括最近由于天坑造成的结构破坏和/或倒塌的案例研究，并评估目前用于喀斯特地区场地特征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. ***
