Aiming at the key joint connection problem between precast beam and pile foundation of fully prefabricated pile-supported wharf,we carry out a joint model test of the grouting connection method,and analyze and compare with the conventional cast-in-place joints to study the reliability of different connection methods.Relying on an actual project,we carry out the structural design of a fully prefabricated wharf,and at the same time,for the installation of large-volume prefabricated beam components on site,we adopt the corresponding design of supporting piles to meet construction requirements.The results show that the joint design scheme of fully prefabricated pile-supported wharf is safe and feasible.Under complex natural conditions,the overall safety of the fully prefabricated wharf can be ensured by adopting joint strengthening measures such as channel steel and corrugated pipe,as well as supporting piles during the construction process.
