CONSOLIDATION AND DEFORMATION ANALYSIS OF WEAK FOUNDATION OF WASTE DUMP IN OPEN PIT MINE

The failure of weak foundation of waste dump is a serious problem in open pit mine. In this paper, considering the characteristic of soft soil, the elast-plastic consolidation and deformation analysis of weak foundation of the waste dump in Waitoushan open pit mine has been carried out. The satisfied results, such as pore water pressures, horizontal and vertical displacements during staged construction, are obtained, and the analytical values can explain well the observed data. It can be applied to other mines where similar problems are presented.
