【摘要】 在清华大学2 000 kN大型静/动三轴试验机上进行了苗家坝水电站砼面板堆石坝筑坝材料的大型三轴动力特性试验,包括动剪切模量与阻尼比试验、动残余变形特性试验、动强度试验等。基于试验结果分析了坝料的动力变形规律,为该工程的应力变形计算和设计施工提供了试验依据。更多还原

【Abstract】 This article presents large-scale triaxial tests on rockfill materials of the 111m high Miaojia dam.The tests are conducted on the large-scale triaxial apparatus in Tsinghua universty to study dynamic modulus and damping ratio,dynamic residual deformation properties and dynamic strength.The results about the dynamic deformation law of rockfills provide experimental basis for engineering construction.更多还原
