Application and Optimization Design of Flexible Docking Piles in Pier Upgrading

Whether fenders need to be set between the flexible dock piles and the quay, and the calculation method of the flexible dock piles with fenders on the front side still need to be studied. Abaqus finite element software was used to analyze the steel pipe piles with fenders on both sides, and it is considered that the piles should adopt p-y curve method, the inner fender is calculated according to the nonlinear spring, and the design of the leaning pile is optimized by combining with engineering examples. The results show that the setting of the inner fender can help reduce the internal force of the leaning pile; the use of high strength steel in the steel pipe pile and the adoption of local reinforcement can significantly improve the performance of the leaning pile.

It is still necessary to study whether fender should be installed between fender pile and wharf and the calculation method of fender pile with fender in front of berth pile. In this paper, Abaqus finite element analysis software is used to analyze the steel fender pile with fender on both sides. It is believed that the fender pile can be installed between fender pile and wharf and the calculation method of fender pile with fender in front of berth pile. believed that the fender pile can be analyzed by p-y It is believed that the fender pile can be analyzed by y curve method, and the inner fender is analyzed by nonlinear spring. The optimal design of the fender pile is carried out by engineering examples combined with an engineering example. The results show that the inner fender is helpful to reduce the internal force of fender pile. The steel tube pile is made of The steel tube pile is made of high strength steel, and the local strengthening of steel tube pile can significantly improve the performance of fender pile.
