摘　　要：结合西安地铁1号线建设,对地铁1号线沿线相关地裂缝进行了细致研究。在资料收集、地面调查的基础上,研究主要采用钻探手段,揭示地裂缝两侧地层形态,进而确定地裂缝位置及性质。研究结果表明:地铁1号线由西向东先后穿越了西安地裂缝f3、f4、f5,其中与f3相交2次;除西安地裂缝外,地铁1号线还穿越了朝阳门外地裂缝和跑马场—纺织城地裂缝,与跑马场—纺织城地裂缝缠绕相交3次;朝阳门外地裂缝以前未曾被发现,钻探剖面显示其断距大,具有西安地裂缝的性质;跑马场—纺织城地裂缝为1条长度超过4km的地裂缝,浐河东西两岸均有出露,活动方式与西安地裂缝相同,应属西安地裂缝范畴。The ground fissures were studied in details along Xi＇an metro No. 1. On the basis of previous research data collection and ground investigation, the research was implemented mainly by means of drilling exploration which could reveal strata situation of ground fissures of both sides and then the fissures＇ locations and characteristics were determined. The results show that the Xi＇an ground fa, f4, f5 cross the metro line, and fa crosses twice. In addition to the Xi＇an ground fissures, two ground fissures, Chao-yang-men-wai and Pao-ma-chang--Fang-zhi-cheng al- so cross the metro line, and the latter intertwines the metro line and passes through it 3 times. The Chao-yang-men-wai ground fissure has not been discovered before. It has the same properties with those of Xi＇an ground fissures and has great displacement of fault according to the drilling profiles. Pao-ma-chang-Fang-zhi-cheng ground of Chanhe River, and has the same activity with in Xi＇an ground fissures＇ category. 1 tab, 5 figs fissure is over 4 km long. It outcrops two banks Xi＇an ground fissures, therefore should be listed , 13 refs.
