摘　　要：深入研究西安地裂缝的形成原因,对于合理有效的减轻和防治地裂缝,具有重要的现实意义。依据大量的监测资料,研究认为西安地裂缝,是由于黄土梁洼处的正断层,在湿陷性黄土、地表水、承压水或潜水水位持续上升的共同作用下,特定的时空条件,在地表自下而上的开裂显露,地铁的开通,对地裂缝的活动也有一定的影响。To further study formed reasons of ground fissures in Xi＇ an, it has great significance for reasonable and effective to mitigate and prevent ground fissures. Based on the mass monitoring data, the ground fissures in Xi＇ an are formed by the normal fault at loess depression gradually exposed, which influenced by collapsible loess, water level rise of surface water and ground water under the specific space and time condition. Metro operation also has influence on the ground fissures movement.

关 键 词：地裂缝 黄土湿陷性 地表水 潜水水位
