摘　　要：桂林园林园艺博览园内可能发生的地质灾害为崩塌滑坡、岩溶塌陷和路基不均匀沉降。根据不同灾种的影响因素及影响力大小,结合相关文献资料和实际工作经验,制定评判标准。运用模糊数学理论中的隶属度函数对建设项目场地进行评估,并通过模型运算和隶属度分析,将该建设项目地质灾害危险性分为大、中、小三个等级,从而建立区域地质危险性评价体系。Geo-hazards that may occur in the construction site of Guilin Garden and Horticultural Exposition are landslide,karst collapse and differential settlement of subgrade.A criteria has been established for risk evaluation based on studying the impact of disaster-triggering factors,relevant literature and practical experience.The construction site is evaluated through the applicdation of membership function of fuzzy mathematics.The construction site is divided into three areas,namely,of large,medium and small disaster risk based on model calculation and membership analysis.A risk assessment system for geological disasters is established.
