| Abstract: | Based on the numerical simulation for the large-diameter cylinder pile's 3D-Circumferential flow under wave-flow co-function by using FVM,this paper analyzes the complicated 3D-torrent near the large-diameter cylinder pile,and gives the 3D-flow distribution,the stress distribution on the surface of cylinder pile and in the bed near the cylinder pile,furthermore,analyzes local scour of wave flow in the bed near the cylinder pile. |
