Evaluation of Static Pile Load Test Results by Numerical Analysis and Interpreting Methods
摘要
Prediction of the ultimate pile capacity and settlement at working load remains one of the key challenges in geotechnical engineering field. Static pile load test result of a large diameter pile is discussed in this paper. The pile load test results are interpreted using various interpreting methods such as Chin’s method, Decourt method, Tangent method, and Kulhawy’s method to arrive at the ultimate pile load capacity. Also, variation of working load based on IS Code is also illustrated. The pile settlement data are back analyzed by analytical methods and 2D numerical modeling. Major influence factors affecting pile capacity such as soil strata, condition at pile toe, soil and pile interface, and drilling fluid are also discussed. This paper highlights the ability of the numerical simulation to get reasonable estimates of the settlements.
