Abstract: Taking the Φ1200δ18 steel pipe pile and Φ1200δ150PHC-steel pipe composite pile on the dock platform as the research objects. In this paper, the self balancing method was used to conduct pile bearing capacity tests to verify the vertical ultimate bearing capacity of the pile foundation, providing reference and basis for the construction, design, and testing of similar steel pipe piles and PHC steel pipe piles.
Keywords: static load test; PHC-steel pipe composite pile; self-balance method; high pile wharf; pile foundation
