Popis: The anti-flood screw pile is difficult to be installed on hard ground. In order to improve the installation characteristics of the screw pile, grooves are fabricated on the conical surface of pile tip. Based on a coupling algorithm of finite element method and smoothed particle hydrodynamics, the software ANSYS/LS-DYNA is used to simulate the process of installing grooved and un-grooved screw pile. It is found that compared with un-grooved pile, the grooved pile tip completely installation time reduce 8.85% and the grooved screw pile installation torque increase by 1.7%. Furthermore, the compaction effects of screw pile to the soil do not have much change before and after grooving. The research results in this paper provide a reference for the optimization of veritable anti-flood screw pile structure design.
