摘要
岩土介质破坏准则具有非线性。运用非线性Mohr-Coulomb破坏准则并运用土体破坏时的速度场和虚功率原理对库仑主动土压力的上限解进行了分析,推导了非线性的库仑主动土压力公式并进行了初步探讨。
the rock and soil failure criterion had the nonlinearity. This article has the upper-bound solution of Coulomb active earth pressure using nonlinear Mohr-Coulomb failure criterion and velocity field of soil and the principle of virtual power, inferred the formula of nonlinear Coulomb active earth pressure and explored it primary.
