基于SMP准则的土的平面应变强度公式

Soil strength equation in plane strain based on SMP

基于ＳＭＰ准则和佐武的平面应变条件，推导了摩擦材料的平面应变强度公式。通过引入粘结应力σ０，推导出适应于ｃ－φ材料的平面应变强度公式。各种试验结果证明了所提强度公式是合理的。

Based on the SMP failure criterion and Satake's stress condition in plane strain state, the failure criterion in plane strains for frictional materials is proposed. This failure criterion is extended to that for cohesive-frictional materials by introducing a parameter of bonding stress σ0.The validity of the failure criterion proposed herein is also verified by various test data.
