摘　　要：基于扩展的SMP准则和佐武的平面应变状态,推导建立了适合各种应力状态下的一般黏性土体的平面应变强度公式。将不同地区的黄土进行平面应变试验和三轴压缩试验,并将两种试验得到的强度参数进行了比较。试验结果表明所提出的强度公式具有一定的参考意义。Based on extended SMP criterion and Satake’s plane strain condition.Plaine strain strength formula,which could be appropriate for various stress states,has been put forward.Plane strain tests and triaxial compression tests of soil on the different areas has been studied,and compared two’s strength parameters.The experimental results show that the strength formula proposed has a certain reference significance.
