    Graphic method of SMP stress state

    • 摘要: 空间滑动面强度准则(SMP准则)根据实体空间的SMP平面上应力状态判断确定试样是否破坏。该准则在三轴压缩和三轴拉伸情况下退化为Mohr-Coulomb强度准则。通过对实体单元的应力状态分析,讨论了SMP平面的空间位置以及SMP平面上应力状态,详细分析了SMP平面上应力状态点在三向应力莫尔圆中的图解方法。
      Abstract: According to the SMP criterion, the ratio of shear stress to normal stress on SMP plane in entity space is employed to determine whether or not the soil sample is damaged. Under triaxial compression and triaxial extension conditions, the SMP criterion degrades to the Mohr-Coulomb one. By analyzing the stress state of a general plane in a cubic soil element under three principle stresses, the location of SMP plane is discussed, and the stress state of the SMP plane is also deduced. After these, the determination procedure of SMP state point in Mohr’s stress circle is introduced.
