ABSTRACT
Static load test (SLT) and the Hybridnamic rapid load test (RLT) were carried out on an open-ended steel pipe pile (SPP) driven in sandy ground. The Hybridnamic RLT is a kind of falling mass type rapid load test, facilitating quick and efficient execution of multiple blows on a pile. SLT was carried out 25 days after pile driving, and RLT was carried out 8 days after the SLT. Static load-displacement curves were estimated from the RLT using various interpretation methods such as the UnLoading Point Connection (ULPC) method, the ULPC invoking Case method (ULPC_CM), and new methods (calleda aß method and aß_CM method). Static load-displacement curves from the SLT and the RLT with the various interpretation methods were compared to discuss the applicability of the various interpretation methods.
