摘　　要：我国是地裂缝灾害严重的国家,尤其是汾渭盆地,地裂缝发育最为典型,灾害较为严重。随着我国高速铁路工程建设的发展,穿越地裂缝灾害区将不可避免,这给高速铁路的建设及建成后的安全运营留下重大安全隐患。以大西客运专线运城盆地沿线具有代表性的地裂缝作为研究对象,对沿线地裂缝的工程地质特征、分布规律、成因、活动性强弱、危险性等级以及随工程地质条件变化可能发生的情况进行了分析与评价,并针对其潜在影响范围内高铁线路的安全性,提出了相应的防治措施和监测控制方法。China is a country with serious ground fissure hazards especially in Fen-Wei Basin. The ground fissures are characterized by typical developments, and serious damages. With the development of China＇ s high speed railway engineering, it is inevitable for them to pass through the ground fissure hazard areas, which leaves serious hidden dangers in the construction as well as safe operation of high speed railway. With the typical ground fissures along the Datong-Xi＇ an traffic line in Yuncheng Basin as the research objects, this passage analyzed and evaluated their engineering geological characteristics, distribution rules, formation, activity strength, risk level and the possible situations in the changing engineering geological conditions. Meanwhile, aiming at the security of high speed railway line within the potential coverage of ground fissures, this passage puts forward corresponding prevention-control measures and monitoring-control scheme.
