摘要： 在无支护和有支护（加设抗滑桩及挡土墙）的条件下开展了降雨对边坡稳定性影响的模型试验研究。以实际工程边坡为原型，在常规重力1 g条件下设计了试验模型。试验结果表明：在 有支挡结构条件下，降雨对坡体竖向和水平位移的影响均很小，表明支挡结构对边坡坡面位移的限制作用明显。通过比较降雨对坡面和内部位移的影响，发现坡面位移变化远大于内部位移变 化，加设支挡结构以后坡体变形主要是雨水对坡面的冲刷造成的。

Abstract: The experimental study on the model of the influence of rainfall on the slope stability was conducted under the condition with existence of support structure (i.e. anti-slide pile and retaining wall) and lack of support structure. A practical engineering slope was taken as a prototype, and the experimental model was designed under the condition of conventional gravity 1g. Test results show that the vertical and horizontal displacements of the slope are slightly influenced by the rainfall with the support structure, which indicates that the support structure has notable limitation to the displacement of the slope. It is found that the surface displacement is much larger than the inner displacement of the slope, by comprising the influence of rainfall on the slope surface displacement and the slope inner displacement. And after setting up the support structure, the deformation of the slope is mainly resulted from the scour of the rain on the slope.
