Abstract

A model for the analysis of subsidence is established to evaluate the ground distortion by using survey data at multiple points,calculation method for subsidence in general terrain conditions,surface deformation in mountain areas,and surface subsidence induced by trip mining,in computer-aided visualization-calculation system. The system primarily makes use of data conversion and transfer between softwares. The system can be used to determine the numerical value of the subsidence along a subsidence basin's alignment or inclination. As well as movement and deformation at any points of the basin area induced by mining. It can be applied to resources and environmental evaluations.
