【Abstract】 The squeezing effect of static pressure pile on soft clay foundation is analysed briefly. The radius of plastic area, the maximum compress stress caused by driving pile ,and the pore water stress can be concluded by using the cavity expansion method and the effective stress theory. On the basis of the engineering practice, several efficient and practical measures to prevent or weaken the effect on surrounding engineer are put forward.更多还原
