以某斜坡桥梁桩基为工程原型,建立了桥梁桩基-斜坡三维有限元计算模型,分析了既有状态和加固状态下因降雨导致的桥梁桩基和斜坡的附加变形;采用强度折减法计算了各工况下的斜坡稳定安全系数。研究结果表明,各项加固措施可有效减小因降雨导致的桥梁桩基和斜坡的附加变形,提高天然状态和降雨状态条件下的斜坡稳定安全系数。

By taking a bridge pile foundation in slope area as the engineering prototype,the author established a bridge pile foundation-slope 3D finite element calculation model,analyzed the additional deformation of bridge pile foundation and slope caused by rainfall in existing state and in reinforced state,and then calculated the slope stability safety factor in each working condition by the strength reduction method. The results show that all reinforcement measures can effectively reduce the additional deformation of bridge pile foundation and slope caused by rainfall,and improve the slope stability safety factor in natural state and in raining state.
