Spatial analysis of slope rock mass of a bridge foundation based on network simulation of continuities

Analyses of the distribution of rockmass discontinuities and their association characteristics are prerequisites for studying stability of rock mass.According to the discontinuity network stochastic simulation method,based on the surveying data of the discontinuities which are on the rock mass’s surface,a numerical model of probability statistics for distribution of discontinuities of rock mass can be established;and a network structural model of discontinuities of rock mass is determined.With the model,3D geometrical forms of free blocks are analyzed;and the possible destruction forms of the blocks are to be pointed out.Meanwhile,the integral stability of block system is to be forecast in macroscopic perspective.
