摘要

基于SMP准则和Lade强度准则，推导出新的无黏性土强度准则表达式，它较好地反映了单个主应力对滑动面的交叉影响，而不是仅局限于中主应力的影响。通过与真三轴试验数据的对比，发现该新准则在π平面上与试验数据较为吻合，优于上述两个传统的强度理论。

Abstract

A new strength criterion was deduced based on the existed strength criteria for cohesionless soil such as the SMP model and the Lade model. It properly reflects the influence of the single principal stress on the mobile surface instead of just being restricted within the influence of the intermediate principal stress. The new criterion can fit the experimental data obtained by the previous study very well and seems to be superior to the traditional ones.
