Both static and cyclic triaxial tests are carried out, with the specimens consolidated under different principal stress ratios. A finite element method is put forward for calculating the cumulative deformation of soft clay under cyclic loading.展开更多

The mechanism of the method is discussed in this paper by presenting a consolidation model under the action of negative pressure. A scheme of using vacuum preloading in designing a gravity platform is proposed to strengthen the soft clay layer on which the platform will be placed. Details of a drainage system are described and the functions of the system are also discussed.展开更多
