【摘要】 太谷地裂缝主要分布在北部平原区。在分析太谷县地裂缝发育特征的基础上,从地质构造、地震、地下水超采和地层等方面,探讨了地裂缝的形成原因。分析得出地层是地裂缝形成的物质基础,基底断裂构造、新构造运动是地裂缝形成的主导原因;地下水的过量开采是地裂缝的关键性诱发因素,并提出了避让、加固、回灌等是防治地裂缝地质灾害的对策。更多还原

【Abstract】 The ground fissure country is mainly distributed in the northern plain area in Taigu.Based on the analysis of development characteristics, this paper discusses the formation reasons between ground fissure and geological structure,earthquake,the situation of groundwater overexploitation and stratum.It is thought that stratum is the material base in the formation of ground fissure.The most important reason is fault structure and new tectonic activity.Excessive recovery to groundwater is the most key risk factor.The countermeasures of the ground fissures were proposed,which were giving away ground fissure,recharging and fixture.更多还原
