| 摘 要： | 太原盆地的地裂于１９７６年出现，至今仍在活动。地震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５０ｋｍ，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震的运动受活动控制，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。

| Abstract: | The ground fissure in Taiyuan basin has appeared since 1976,and has moved to this day.The ground fissure mainly distributes in the belt from Yuci to Qixian of the downthrow side of east bordered fault of the basin,the ground fissure belt intermittently stretches to 50 km;secondly,distributes near the area of Xinghua village of Fenyang county of the piedmont fault of the basin.The space location and the fissure movement of the ground fissure belt are controled by the tectonic movement,and the occurrence time and the development stage are influenced by the overexploitation of the underground water and the strong precipitation process.The formation and development of the ground fissure of Taiyuan basin are the result of the comprehensive efforts of many agents under the effect of the present regional stress field. |
