Shallow features of jingyang-weinan fracture analyzed by Artificial seismic exploration method—Taking the gaoling portion of xi'an metro line 10 as an example

Many fault zones in Xi’an area produce many secondary ground cracks, which have a great impact on engineering construction. In this paper, the characteristics of faults are analyzed by means of investigation, artificial seismic drilling and geological drilling, making clear that the Jingyang-Weinan fault（Gaoling section） has a strike N57 ° W,trend NE33 °, a dip angle 70 ° and a vertical fault distance ranging between 3m and 10m above 60 m to shallow. The fault is a Holocene active fault with a slip rate 0.18 mm/a.
