摘要      西安地铁四号线是西安市轨道交通线网中的十字骨架，是线网中的骨干线路，它穿越了14条活动的地裂缝带。为进一步研究西安地裂缝，给地铁线路沿线地裂缝的防灾减灾提供科学依据，本文通过野外地质环境和地质灾害调查,着重查明了西安地铁四号线沿线的14条地裂缝的发育特征；并根据近些年的监测成果资料对地裂缝的活动性进行了分析总结，预测了其活动趋势；采用定量计算的方法确定了地裂缝对地铁线路的影响范围，并在综合分析地铁线路危害特点的基础上确定了地裂缝与线路相交段的危险性等级，最终将与地铁四号线相交的地裂缝划分为Ⅰ级、Ⅱ级、Ⅲ级三个等级。地裂缝灾害是西安主要的地质灾害，在地铁建设中要给予高度重视。

Abstract： The Xi'an Metro line 4 is the vertical trunk of the Xi'an rail transit network and passes through 14 active ground fissures. In order to perform further research on ground fissures and provide a scientific basis for preventing and reducing the hazards along the Xi'an Metro line 4, this article focuses on identifying the development characteristics of the 14 ground fissures along the Xi'an Metro line 4 through geological environment and geological hazard surveys, and by analyzing and summarizing the activities of the ground fissures based on surveying results obtained in recent years in order to predict their future activity. The zone of this metro affected by ground fissures was determined by quantitative calculation. Meanwhile, the risk level at the intersection of the fissure and the metro line was determined by analyzing the risk characteristics along the metro. Finally, the ground fissures along the Xi'an Metro line 4 were classified into level Ⅰ, level Ⅱ, and level Ⅲ fissures. The ground fissures are major geological hazards in Xi'an, and this should be taken into consideration during construction of the metro.
