STUDY ON THE RESPONSE OF PORTAL WATER INJECTION SHEET PILES UNDER STATIC/SEISMIC LOADS
Portal water injection sheet pile is a new type of space-retaining structure. When static loads are applied, its design and calculation mainly follow the method for double-row piles in pit excavation, and some positive results have been achieved. However, its dynamic characteristics and responses under seismic loads have never been studied before. To further the study on the newly developed portal water injection sheet pile under seismic loads, this paper adopts the nonlinear calculation module of FEM software ANSYS. A model for the interaction between the soil and the sheet piles is set up, and the seismic response analysis for this type of space-retaining structure is performed. The effects of the embedded depth and the distance between the front pile and the back pile on the dynamic characteristics of the portal water injection sheet pile are studied. Results show that both the embedded depth and the pile distance have little effect on the dynamic, and as is different from the situation of static analysis.
