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. ***

9612675这项RPG研究是一项初步研究，它将导致对容易被污水坑形成的地点的基础进行系统的风险评估方法。 这种方法将结合特征，准备和设计，以评估在喀斯特地形上建造的结构风险（例如建筑物，高速公路和挡土墙）。 经过文献综述，将评估标准的风险评估方法，以确定哪种方法或混合方法最适合系统方法分析。 该研究将包括最近由于污水坑引起的结构损害和/或崩溃的案例研究，并评估用于表征位于喀斯特地区的地点和设计基础的当前方法的局限性。 ***
