摘　　要：以实际采集的深部岩体试样的岩石力学实验为基础,探讨了花岗岩岩石力学参数随深度变化的基本规律,提出了花岗岩岩石的弹性模量E,抗压强度σC,抗拉强度σt均随岩体赋存深度的增大而增大的观点,给出了花岗岩岩石的弹性模量E,抗压强度σC,抗拉强度σt随岩体赋存深度的增大而增大的数学模型。Based on the rock mechanical test of the underground rocks, this paper probes into basic law of the rock mechanical parameters variations with covered depth about the granite. It advanced a viewpoint that the elastic modulus E, the compressive strength cr C and the tensile strength or C of the granite all increased with the covered depth . It gives mathematic models of the elastic modulus E, the compressive strength cr C and the tensile strength cr C of the granite increased with the covered depth .
