Abstract
The construction of Gaoshan tunnel on Qianjiang-Zhangjiajie-Changde Railway to DK53 + 678 reveals a giant cave,and the shape and distribution of the cavity are extremely complex,and the difficulty of the construction and safety risk are very high.In order to find out the development characteristics and the influence of the cave,the characteristics of the karst surface and the recharge and excretion characteristics of groundwater are identified by means of geological survey,drilling,geophysical and 3D laser scanning,and the stability of the roof and the wall is evaluated.The results provide an important geological basis for the formulation of the treatment scheme of the cave.关键词
