Application of filling pile in reinforcement of wharf structure |
| |
| Abstract: | As a mature technology,filling pile had been widely applied in the new constructions,and it′s feasible to reinforce the wharf structure.By examples of engineering,this paper summarized and discussed the applications and related techniques of filling pile on reinforcing structure of caisson wharf,block wharf,sheet-piled wharf and high pile wharf.The technology which can improve toe resistance of filling pile with semi-closed steel pile end is also introduced.Finally,the merits and demerits are analyzed and summaried about application of filling pile in reinforcement of wharf structures. |
