太原盆地是我国近年来地裂缝灾害最为活跃的地区之一,其成因受多种因子控制。研究以区域地质环境背景条件为基础,系统地分析区内地裂缝的时空分布规律。然后从地裂缝的时空分布规律出发,以主要影响因素为标准,将区内地裂缝分成采空塌陷成因地裂缝、地下水超采成因地裂缝及断裂活动成因地裂缝三种类型。在此基础上系统地分析各成因地裂缝的形成机制,并提出切实可行的防治对策。
Taiyuan Basin is one of the most active ground fissure disasters in recent years in our country. Its causes are controlled by many factors. Based on the background of regional geological and environmental conditions, the study systematically analyzes the spatial and temporal distribution of ground fissures in the area. Then, based on the spatial and temporal distribution of ground fissures, the main factors of fissure are divided into three types: ground fissures of ground-subsidence causes, ground fissures of groundwater over-exploitation and ground fissures of fault activity. On this basis, systematically analyze the formation mechanism of all causes of ground fissures and put forward practical control measures.
