Researching new methods continuously in engineering. Excepting to find the better ground improvement method having superior effects. Plate shear could provide the horizontal shear, and it causes grain of soil to displace aside. It should be helpful to combine grain closely.
The purpose of study is to probe into how the action of plate shear influences on the relative density of the soil. And by way of changing water content、normal stress、grain、initial relative density、method of plate shear to probe into the influence of each term on the changing of relative density of the soil after plate shear. Besides, they probe into how plate shear could improve the depth and how the relative density may change with different depth. Excepting to understand if plate shear is possible to put in situ.
According to the result of the study, plate shear could promote the relative density of the ground. But it is better to improve of low ground than of deep ground. The depth of improvement will increase with the normal stress. But finally, the relative density will be influence by water content、normal stress、grain、initial relative density、method of plate shear, having no relationship with the initial relative density.
