摘　　要：西安地裂缝是西安地区与秦岭山前长安—临潼断裂有关的一组NE-NEE走向的南倾陡倾角正断面的地表反映,它形成了特有的黄土梁洼地貌。西安地裂缝属于一种地质灾害,在工程建设中也是一种岩土工程问题。工程勘察中应采用合理的手段,按规定的精度要求查明地裂缝的位置、分布,为工程建设提供依据。Xi＇an ground crack is a reflection of the ground for a group normal faults with strike NE-NEE and high angle dipping to south, which is related to Chang＇an-Lintong fracture in front of Qinling mountain. It causes special loess ridge and depression geomorphic feature. Xi＇an ground crack is a geological disaster and a geotechnical problem, too. Position and distribution of ground crack should be investigated by using reasonable method and stipulated precision in order to provide basis for engineering construction.
