| 摘 要： | 基于广义非线性强度理论,提出了一种新的变换应力方法,将广义非线性强度理论变换为另一应力空间内的Mohr-Coulomb准则。在新的线性变换应力空间内,材料的强度特性符合Mohr-Coulomb准则,从而广义非线性强度理论可在新应力空间内以Mohr-Coulomb准则的形式应用。通过在新的线性变换应力空间内对2种黏土的强度、应力-应变关系试验结果的分析验证了此变换方法的有效性。

| Abstract: | A linear transformed stress space method is proposed. The generalized nonlinear strength theory (GNST) is transformed into Mohr-Coulomb criterion in the new proposed stress space. Thus, the GNST can be regarded as Mohr-Coulomb criterion in new stress space. The strengths and stress-strain experimental results of two kinds of clay are collected and analyzed in the new linear transformed stress space. The consistency between the experimental results and the theoretical predictions shows that the transformed stress space method is effective. |
