Interpreting End-Bearing Pile Load Test Results


Interpretation of pile tip settlement behavior obtained from rod telltales on fourteen full-scale test piles at five different sites indicates that the applied load can be divided into end-bearing and skin friction components. The end-bearing component is used to obtain stiffness information about the bearing stratum. An equation for estimating pile settlement based on information accumulated during this study is given, and a procedure is proposed to estimate settlement from downdrag forces. Information about bearing strata obtained from the load test results can be accumulated and used to assist with design of future end-bearing pile foundations.
