| 摘 要： | 我国西南地区地势复杂,内河水位变化幅度很大,水位的变化使得内河码头的边坡含水量产生变化,由此引起的边坡水流渗透对码头的稳定性会造成很大的影响.采用理想弹塑性模型和摩尔库伦屈服准则进行数值模拟,通过对架空斜坡式码头岸坡在水位变化条件下的稳定性分析,得出了水位下降过程中各种因素对岸坡的影响;同时发现,岸坡岩土材料的黏聚力对岸坡的稳定性影响要大于内摩擦角.

| Abstract: | Because of the complex topography in southwest region of China,the water level of the inland river has a large amplitude of variation which causes a frequent diversification of the water content in the river slope.The flow caused by the infiltration of the terminal slope stability will induce a great impact on the slope stability of wharf.This paper uses an ideal elastic-plastic model and the Moore Coulomb yield criterion for numerical simulation.Through the bank slope stability of the overhead-type termina... |
