摘要
胶凝砂砾石坝作为一种新坝型在水利工程建设领域得到日益广泛的应用,其抗震设计是极其重要的课题。文章以辽宁省拟建的双龙水电站胶凝砂砾石大坝为例,利用三维有限元模拟的方法对不同材料参数、地震峰值加速度以及地基弹模对胶凝砂砾石大坝的动力反应影响展开研究,结论对促进胶凝砂砾石坝设计建设具有重要的理论和实践价值。
As a new type of dam,cementitious sand-gravel dam has been widely used in the field of water conservancy engineering construction.Seismic design is an important subject.Taking Shuanglong hydropower station planning to build in Liaoning Province as an example,the paper studies the influence of different material parameters,seismic peak acceleration and elastic modulus of foundation on the dynamic response of cemented sand-gravel dam by means of three-dimensional finite element simulation,the conclusion has important theoretical significance and practical value for promoting the design and construction of cemented sand-gravel dam.
