摘要
降雨会影响土体的力学参数,通过ABAQUS对雨水入渗的瞬态渗流对土坡应力、应变的影响进行研究,以一理想边坡作为案例进行建模与计算,不考虑降雨积水的影响,认为静水压力随深度线性增加,建立CPE4P网格进行计算。后处理中,对其渗透率、孔压、横纵向位移、偏应力、塑性应变以及应力路径等作了分析,得出一系列降雨入渗作用下应力、应变及稳定性的相关结论。
Rainfall affects the mechanical parameters of soil, the influence of rainwater infiltration transiesoil slope stress and strain is studied through ABAQUS. On the basis, an ideal slope is regarded as a case for modeling andcalculation. The influence of rainfall and water accumulation is not considered. It is believed that increases linearly with depth, and a CPE4P grid is established for calculation. In the post- processing, the permeability, pore pressure, horizontal longitudinal displacement, deviatoric stress, plastic strain and stress path, etc. are analyzed, and a series of related conclusions of stress, strain and stability under rainfall infiltration action are obtained.
