Abstract：Research purposes:Xi' an ground fissure is a regional disaster geological phenomena，already constitute a hazard to the Xi' an City. In order to identify the distribution of the ground fissures along Xi' an metro line 6 and its relationship with the line，so as to provide basic information for determining the metro line，station location and construction method of laying the ground fissures. The investigation of three types of ground fissures site is difficult，and there is no mature experience. In order to make ground fissure drilling targeted，reduce the amount of drilling，thereby improve the quality of the survey，accelerate the survey progress along the line laid artificial seismic exploration in order to determine the crack from deep and provide guidance for the ground fissure drilling.
Research conclusions:(1)In this paper, as to complexity of the three types of ground fissures site，first use 18 tons of artificial shallow seismic source seismic reflection prospecting, second drill and verify seismic anomalies，to find out the ground fissures.(2)Seismic tests showed the ground fissures positions which are interpreted by the obvious physical differences agree well with the drilling results. It is one of the effective and credible means.(3)The use of large tonnage vibrator vehicle under urban road environment，interference effects，exploration accuracy and depth have reached the expected requirements，which can be used in the ground fissure investigation. (4)It is also a demonstration and guidance on the survey of concealed fault.
