	1	基于GCTS空心圆柱扭剪仪的四向振动模拟SV波斜入射动力分析显示文摘利用GCTS空心圆柱扭剪仪,采用四向振动模拟SV波斜入射,模拟地震荷载引起的复杂应力状态下土体的动力特性.通过理论计算给出了单位周期内主应力方向角的变化曲线,进而比较不同频率、不同入射角等不同应力路径下动变形的响应,分析该仪器以及加载方式在实现复杂应力状态下土体的动力特性的可行性.	赵瑞斌陈静静毕铭曾西	2017	天津城建大学学报2017，23，6：	1
	2	Critical Cyclic Stress Ratio of Undisturbed Saturated Soft Clay in the Yangtze Estuary under Complex Stress Conditions显示文摘There exists a critical cyclic stress ratio when sand or clay is subjected to cyclic loading. It is an index dis-tinguishing stable state or failure state. The soil static and dynamic universal triaxial and torsional shear apparatus de-veloped by Dalian University of Technology in China was employed to perform different types of tests on saturated soft marine clay in the Yangtze estuary. Undisturbed samples were subjected to undrained cyclic vertical and torsional coupling shear and cyclic torsional shear after three-directional anisotropic consolidation with different initial consoli-dation parameters. The effects of initial orientation angle of major principal stress, initial ratio of deviatoric stress,initial coefficient of intermediate principal stress and stress mode of cyclic shear on the critical cyclic stress ratio wereinvestigated. It is found that the critical cyclic stress ratio decreases significantly with increasing initial orientation angle of major principal stress and initial ratio of deviatoric stress. Compared with the effects of the initial orientationangle of major principal stress and initial ratio of deviatoric stress, the effect of initial coefficient of intermediate prin-cipal stress is less evident. Under the same consolidation condition, the critical cyclic stress ratio from the cyclic cou-pling shear test is lower than that from the cyclic torsional shear test, indicating that the stress mode of cyclic shear has an obvious effect on the critical cyclic stress ratio. The main reason is that the continuous rotation in principal stressdirections during cyclic coupling shear damages the original structure of soil more than the cyclic torsional shear does.	刘功勋栾茂田唐小微王忠涛郭莹	2010	Transactions of Tianjin University2010，16，4：	0
