SELECTION OF SHEAR PARAMETERS OF ROCKMASS FOR BAOQUAN PUMPINGSTORAGE POWER STATION

This paper discusses the method of selecting the shear parameters of rockmass for Baoquan Pumping Storage Power Station from the data of shear test at the station site. The formulas of numerical characteristics of C and f are derived. The results of comparison and analysis prove that the random fuzzy method is more realistic and appropriate because the shear parameters of rockmass are of the randomness and fuzziness, and the formulas of numerical characteristics suggested in the paper can verify the variation and correlativity of C and f.
