In view of the problem that there is no systematic guidance for the design and construction of temporary clip structure of piles for pile supported wharf at present,we study the elevation determination for temporary clip structure under strong wave condition based on an actual project case,and apply the physical model test to measure the wave force of the clip structure at different elevation.We determine the elevations for the temporary clip structures of piles at two stages of construction according to the schedule,which are calculated by finite element analysis software.It achieves good effectiveness on site,which can provide references for the similar projects.
