Abstract

Dynamic grouting in saturated sand was simulated with finite element method. During simulation, covering and superimposing yield surface model was used and large displacement and large strain were considered. The results show that when the dynamic load acts on the bottom or the wall of grouting hole, both the residual pore water pressure and peak pore water pressure will increase. The more the dynamic load, the more the residual pore water pressure and peak pore water pressure. During dynamic grouting, the radial displacement of node in the middle of grouted section was the biggest and became smaller towards two ends.

Key words
