摘要
本文介绍用双向振动的动力扭剪仪模拟海洋波浪的加载形式，通过系统试验和对动主应力轴旋转和常规动扭剪试验结果的对比表明，考虑动主应力轴旋转，砂土的动强度将降低１５％左右．
This paper introduces the way to simulate the cyclic stress characteristics of sand on scabed in a cyclic torsional shear apparatus. The results of systematical test show that the dynamic strength of sand under cyclic rotation of principal stress directions is about fifteen percent lower than that in conventional cyclic torsional shear tests.
