摘要
碾压混凝土重力坝中存在的薄弱层,会对坝体质量产生严重影响。文章以新疆和静县的小山口水电站大坝碾压混凝土坝段为例,通过构建ANSYS三维有限元模型,利用数值模拟的方法,研究了坝体薄弱层对大坝渗流和层间稳定性的影响。结论显示,薄弱层的存在会显著影响坝体的抗滑稳定安全,建议加强碾压层的凿毛和砂浆摊铺管理,以防止薄弱层的产生。
The weak layer in RCC gravity dam will affect the dam quality seriously.This paper takes the RCC dam section of Xiaoshankou hydropower station in Hejing County of Xinjiang as an example, through the construction of ANSYS three-dimensional finite element model and the use of numerical simulation method, studies the influence of weak layer on the seepage and inter layer stability of the dam.The conclusion shows that the existence of weak layer will significantly affect the stability and safety of anti-slip dam.
