| 摘 要： | 自20世纪90年代以来，山西省霍州西部地区出现了大量地裂缝，破坏了许多房屋和耕地，并且改变了地下水资源的空间分布，严重影响了当地人民的日常生活和地区经济发展。由于该地区地裂缝的成因尚不清楚，防治措施难以制订，其影响范围内的人群、房屋、耕地、水资源仍然受着地裂缝地质灾害的威胁。基于此种状况，在调查霍州地区采空塌陷地裂缝时空分布的基础上，结合区内区域地质、水文地质、工程地质及人类经济工程活动等条件，分析了地裂缝形成的主要原因。分析结果认为，采煤形成的采空区和采煤排水造成的地下水位下降是地裂缝形成的主要原因，雨水的冲蚀加速了地裂缝的扩展，确定了该地区地裂缝的非构造属性，并据此提出了相应的治理措施。

| Abstract: | Since the 1990s, hundreds of ground fissures have occurred in western Huozhou area of Shanxi Province in Northern China. The fissures and related subsidence have damaged to houses, agricultural land, and groundwater resources. In this paper, the temporal and spatial distributions of the ground fractures were investigated. The essential factors of cracks were studied with the regional geology, the geological circumstance, hydrogeology condition, and human activity, The results show that the mine goaf and the fall of groundwater level are the essential factors, and the precipitation accelerates the development of the cracks. Based on this, corresponding prevention and control measures are presented. |
