To solve the problems of low construction efficiency and uncontrollable quality of the cast-in-situ construction system in ship lock engineering,the prefabricated structures are applied to retaining wall engineering,and the reinforcement cluster connection is applied to prefabricated retaining wall structures.To clarify the mechanical performance of the connection,this paper conducts unidirectional loading tests on the specimens of the connection to observe the failure characteristics and crack development rules.The test results show that the failure mode is small eccentric tension failure,and the failure location is concentrated at the end of the inserted bar.The research results can provide theoretical support for the failure mode analysis and tensile bearing capacity calculation of the cluster connection in ship lock retaining wall engineering.
