Macro-Mechanical Parameters Analysis of Rock Slope Based on the Partition Classification Method

Article Preview

Abstract:

Accurate mechanics parameters are the precondition of reasonable calculation in the finite element method to calculate the deformation and stability of the rock mass engineering stability. Partition classification method can be used in the simulation of macro-mechanics parameters of rock mass, for the distribution of multiple sets of multi-level joint fissure in some engineering rock, the parameters of the rock mass can be simulated using the numerical method step by step or by group. Based on the partition classification method, the paper simulated the macro-mechanics parameters of natural slope upstream the left bank toe board of Maerdang hydropower station. The slope is divided into three areas according to the rock types and intensity, weathering degree, fracture, the trend and tendency of the fault, spacing and connected rate of the structure surface, the mechanics parameters of the structure surface, the groundwater conditions, and then use the partition classification method to calculate the region's macro-mechanical parameters, the results can be used to provide amount of reasonable parameters for the stability calculation of the slope in the subsequent deformation.
