杭州市富阳区万市镇地质灾害发育特征及影响因素分析

Development Characteristics and Influencing Factors of Geological Hazards in Wanshi Town,Fuyang District,Hangzhou

为进一步摸清富阳地区城镇地质灾害发育现状,保障居民人身财产安全,通过原始资料分析和野外调查结果,摸清了万市镇地质灾害的类型和发育特征,通过资料分析对比得出了地形地貌、工程地质岩组、地质构造、降雨和人类工程活动等因素对地质灾害发育的影响作用,查明研究区地质灾害规模为小型,地形地貌、地质构造、工程地质岩组起控制作用,降雨及人类工程活动是主要诱因,为万市镇乃至富阳区地质灾害的预警预防及治理提供参考。

In order to further understand the development status of urban geological hazards in Fuyang area and ensure the personal and property safety of residents,the types and development characteristics of geological hazards in Wanshi town were found out through analysis of original data and field investigation results.Through data analysis and comparison,the influences of landform,engineering geological rock groups,geological structures,rainfall and human engineering activities on the development of geological hazards were obtained.It is found that the scale of geological disasters in the study area is small,the topography,geological structure,engineering geological rock group play a controlling role,while the rainfall and human engineering activities are the main causes,which provides a reference for the early warning prevention and control of geological disasters in Wanshi town and even Fuyang District.
