宝泉抽水蓄能电站岩体抗剪参数的选取

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

本文讨论了岩体抗剪参数Ｃ、ｆ值的选取方法，推导了Ｃ、ｆ值的数字特征公式。通过对宝泉抽水蓄能电站工程岩体抗剪参数的选取，结果表明：由于岩体抗剪参数具有随机性和模糊性，采用随机－模糊法选取的Ｃ、ｆ值要符合实际；文中给出的数字特征公式可对Ｃ、ｆ值的波动性及相关性进行检验。

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.
