在平面应变条件下,分别推导了松冈元-中井照夫破坏准则、Lade-Duncan破坏准则和俞茂宏双剪统一强度准则的表达形式,并将平面应变条件下和常规三轴压缩条件下的土体抗剪强度指标联系起来.在此基础上,得到了考虑中间主应力影响的主动土压力计算公式.计算表明,只要填土的内摩擦角大于0,考虑中间主应力影响的主动土压力值都小于Rankine主动土压力值,但不同的破坏准则,其计算结果相差较大.
- Abstract:
-
Under plane strain conditions, the expression forms of Matsuoka Moto-Nakai Teruo failure criterion, Lade-Duncan failure criterion and Yu Maohong double shear unified strength criterion were derived, and the soil shear strength index under plane strain condition and conventional triaxial compression condition was linked. On this basis, the active earth pressure calculation formula considering the influence of intermediate principal stress is obtained. The calculation shows that as long as the internal friction angle of the filled soil is greater than 0, the active earth pressure value considering the influence of the intermediate principal stress is smaller than the Rankine active earth pressure value, but the calculation results differ greatly depending on the failure criteria.
