摘要：
Based on the theory of plastic mechanics, the relationship between the softening modulus and confining pressure were obtained using the three axis test method. The strain-softening model of mudstone was established considering the influence of confining pressure. Based FLAC3D development platform, the model in practical engineering was validated. The results show that the strain-softening model of mudstone considering the effect of dilatancy angle can react the nonlinear mechanical behavior of rock, and provide the basis for the realization of the quantitative to qualitative change. Practical application shows that the numerical results agree with the actual situation. © 2016, Editorial Board of Journal of CUMT. All right reserved.
