摘要
对瀑布沟水电站地基砂层土料进行室内动力三轴试验,研究土体在复杂和高应力状态下的动模量阻尼比、动力残余剪切变形及残余体积变形特性,确定动力变形计算参数和强度指标,为大坝抗震复核提供参数。
Pubugou sand soil foundation material was test by indoor dynamic triaxial test,it researched the damping ratio,dynamic shear deformation and residual volume residual deformation under the complex and high stress state,and determines the dynamic deformation calculation parameters and intensity indicators,provides parameters for dam seismic review.
