黄土边坡的侵蚀破坏是引起黄土地区公路边坡自然灾害的主要诱因。通过建立室内边坡降雨冲刷物理模型，进行黄土边坡侵蚀破坏的模拟试验，再现边坡溅蚀、片蚀、沟蚀、坍塌的基本破坏过程，并对坡面降雨冲刷的演变过程和侵蚀机理进行了细致的描述和分析。试验表明：在一定的降雨雨强下，径流 TSS（携砂能力）和单位面积侵蚀泥沙量随着试验坡度的增加逐渐增加，而径流总量、侵蚀干泥沙量随着坡度的增加而相应变小。同时，黄土边坡侵蚀冲刷过程中的主要侵蚀能力参数如坡面径流总量、汇流干泥沙量、侵蚀干泥沙量等与降雨雨强之间存在相应的关系。

The erosion is the main cause of natural disasters of the loess highway slope.This paper uses the slopeerosion experiment with simulated rainfall model.It can reproduce the splash erosion slope,sheet erosion,gullyerosion,and collapse of basic failure process of slope.It can make detailed description and analysis of the processof erosion.The experiment shows that erosion sediment per unit area increase gradually with the increase ofexperiment slope and total runoff.The erosion sediment decreases gradually with the increase of experiment slope.Meanwhile,there is a corresponding relationship among the main parameters of loess slope erosion such as totalerosion runoff,confluence sediment,erosion sediment,and rainfall intensity.
