| 摘 要： | 基于统一强度理论和非饱和土双应力状态变量抗剪强度,合理考虑中间主应力效应,推导了平面应变条件下非饱和土双应力状态变量抗剪强度统一解,进而考虑中间主应力、特别是基质吸力高低的不同影响,建立了非饱和土主动、被动土压力和任意侧压力系数下均适用的条形地基临界荷载解析解.本文解析解具有广泛的理论意义,根据实际工程具体情况,可进行...

| Abstract: | Based on the unified strength theory and the shear strength of unsaturated soil in terms of two state stress variables,the unified solution of shear strength for unsaturated soil under the plane strain condition is derived by taking into consideration the effect of the intermediate principal stress rationally.Analytical solutions for unsaturated soil of the active earth pressure,the passive earth pressure and the critical bearing capacity for strip foundation suitable for any lateral pressure coefficient ar... |
