Prefabricated steel utility tunnel is a kind of structure for rapid construction,and is usually con-structed with corrugated steel.As a new type of structure,its structural properties is important for design and application.Combined with actual project,this paper carried out full-scale test research on the double-chamber prefabricated utility tunnel.The bearing capacity and deformation capacity of the structure under different load-ing conditions was investigated,and the working performance and safety performance of the joint was studied.It provided a reference for design and application of underground prefabricated structure.
