摘要：In this paper,a physical base friction test model of a slope is *** model is based on similarity principles and the geological co.ditions of a co.plicated bridge slope during co.struction,deformation and *** behavior of the slope in both its natural state and during excavation loading is qualitatively analyzed through base friction *** base friction test results are then subjected to co.parison and analysis using finite element numerical *** findings show that the whole engineered slope tends to stabilize in its natural state,whereas instabilities will arise at faulted rock masses located near bridge piers during excavation ***,to ensure normal co.struction operation of bridge works,it is suggested that pre-reinforcement of faulted rock masses be performed.
