Evaluating the Thickness of the Security of the Carve Roof Based on SIGMA/W in a Karst Area
With the engineering constructing in the karst area, there is a serious problem on the thickness of the security and deformation of the cave roof. In this paper, it conclusive the degree of the karst development not only influenced by the structure of earth but also influenced by the type of rock and groundwater. The collapse of the karst is influenced by the development of the karst thickness of the quaternary, the intensity of the mining groundwater and water level.
