摘　　要：动荷载作用下等压固结饱和粘土的孔压模型已有很多,而偏压固结的动孔压模型却鲜见于文献。根据摩尔-库仑极限平衡原理,推导了非等向固结状态下振动孔隙水压力极限值公式,建立了循环荷载作用下偏压固结饱和粘土的孔压数学模型。通过试验验证,所提出的孔压模型是合理的。The excess pore - water pressure model of isotrepic consolidated saturated clay can be found in many documents, while the excess pore - water pressure model of anisotropic consolidated saturated clay is less studied. Based on the Mohr- Coulomb critical equilibrium theory, the formula of critical pore pressure of anisotrepic consolidated saturated clay under cyclic loading is deduced. The excess pore - water pressure model of anisotropic consolidated saturated clay under cyclic loading is proposed in this paper. According to the undrained cyclic triaxial tests, the proposed model is verified available.
