Abstract: In order to study the soil squeezing effect of Taper-cylinder with holes combined pipe-piles, a group pile test was conducted on Taper-cylinder with holes combined pipe-piles to obtain the spatial and temporal dissipation law of super-pore water pressure caused by sinking piles. Based on the indoor model test, the excess pore water pressure caused by the Taper-cylinder with holes combined pipe-piles group pile sinking was detected and analyzed. The results showed that by increasing the number of holes in the pile body and reducing the taper, the peak of excess pore water pressure caused by the sinking of Taper-cylinder with holes combined pipe-piles could be reduced by 13.96%~17.94%. The dissipation speed of excess pore water pressure increased with the increase of depth and decreased with the increase of radial distances. Otherwise, compared with other hole layout methods, the pipe-piles with star-shaped hole layout method exhibited smaller peak value of excess pore water pressure caused by pile group sinking and faster dissipation speed. In conclusion, the Taper-cylinder with holes combined pipe-piles would be able to improve the construction quality and stability of pile foundation, and the research results could provide some reference for the engineering application of Taper-cylinder with holes combined pipe-piles.
