中文摘要：

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。

英文摘要：

This Paper briefly introduces regional geological environment background of Shunyi District in Beijing,and preliminarily studies the main features of ground fissures and systematically analyzes the factors and mechanism of ground fissure disaster at last.Regional geological structure,depth and relief form difference of bedrock,thickness and distribution of Quaternary sediment are the intrinsic factors that give rise to the ground fissures disaster,and the super-pumping groundwater is the extrinsic factor.Thus,a few pieces of preventive advice and measures are proposed.
