太原盆地的地裂于 1976年出现 ,至今仍在活动。地裂主要分布于盆地东部边界断裂附近下降盘一侧的榆次至祁县一带 ,地裂带断续延伸达 5 0 km,其次是分布于盆地西侧汾阳县杏花村一带山前断裂附近。地裂带空间位置和地裂的运动受构造活动控制 ,而地下水的过量开采和强降雨过程又影响地裂发生的时间、地段和发育程度。太原盆地地裂的形成和发展是现今区域应力场作用下多种因素综合作用的结果。 The ground fissure in the Taiyuan Basin occurred in 1976 and is still active. The ground fissures are mainly distributed in the Yuci-Qixian area on the side of the downdrop near the east boundary fault of the basin. The fissure zone extends intermittently up to 50 km, followed by the piedmont fault in Xinghuacun, Fenyang County, west of the basin . The movement of the position of the fissure zone and the ground fissure are controlled by the tectonic activities, while the over-exploitation of groundwater and the heavy rainfall process also affect the time, location and degree of development of the fissure. The formation and development of the ground fissures in the Taiyuan basin are the result of the combined effect of various factors under the regional stress field.
