Research on the Causes of Surface Collapse in Jiandou Town,Anxi County

近年来,安溪县地面塌陷灾害日益严重,已危害工程建设及人员生命财产安全。通过分析安溪县剑斗地区的地质环境条件及地面塌陷的特征、影响因素和形成条件,认为地面塌陷与溶洞、地下水、第四纪盖层厚度、地质构造、地下开采活动等因素相关,并分析了地面塌陷的形成机理,提出了防治建议。

In recent years, surface collapse disaster has been becoming increasing serious, and has caused the great threat to the safety of engineering construction and people＇s lives and property. This paper analyzes the geological conditions, and the characteristics, influencing factors and forming conditions of surface collapse disaster in Jiandou town, Anxi county, considers that the surface collapse is relevant to karst cave, underground water, the thickness of the Quaternary overburden layer, geological structure, underground mining, etc, analyzes the forming mechanism of surface collapse, finally, proposes some prevention countermeasures.
