摘　　要：自然灾害对人类的生命财产安全危害性很大,尤其是隐伏在城市下面的活动断层引发的直下型地震,对城市的破坏性更为严重。在整理前人区域地质资料和野外地质点调查成果的基础上,对深圳市区域应力场进行了有限元模拟,将其稳定性划分为稳定和较稳定两个级别,评价结果显示稳定区面积1107km^(2),较稳定区面积890km^(2),评价结果可为城市规划和建设提供参考。Natural disasters pose significant threats to human life and property,particularly down-straight earthquakes triggered by active faults concealed beneath the city.In this paper,the regional stress field of Shenzhen city is simulated by finite element method on the basis of previous regional geological data and field survey results,and its stability is divided into two levels:stable and relatively stable,The evaluation results indicate a stable area of 1107 km^(2) and a relatively stable area of 890 km^(2).The evaluation results can provide reference for urban planning and construction.
