从区域特定的地质环境背景出发,对北京顺义区地裂缝的主要特征进行了初步研究,系统分析了地裂缝地质灾害的成因机制,即区域地质构造、基岩埋深及基岩起伏形态差异、第四纪沉积层厚度及空间分布差异引发地裂缝灾害的内在条件,而长期过量开采地下水是诱发地裂缝灾害的外在因素,并据此提出了几条防治的建议和措施。 Based on the background of regional specific geo-environment, the main characteristics of ground fissures in Shunyi District of Beijing were studied. The genetic mechanism of ground fissure geological disasters was systematically analyzed, namely the regional geological structure, the bedrock depth and the differences of bedrock undulations, Quaternary sedimentary layer thickness and spatial distribution of the differences lead to the inherent conditions of ground fissure disasters, and long-term over-exploitation of groundwater is an external factor induced by ground fissures, and put forward several prevention and control recommendations and measures.
