Analysis of Lateral Load Tests on Auger Cast Piles
This paper evaluates three lateral load tests performed on 406 mm (16-inch) diameter auger cast piles (ACP). The lateral deflection values of the ACP measured in the field are compared with the lateral deflection values of the ACP predicted using a commercial computer program, LPile. The predictions were made assuming the linear, as well as the non-linear, variation of the flexural stiffness of ACP. A sensitivity analysis was performed to determine the effect of various soil parameters on the lateral deflection of the ACP. The sensitivity analysis indicated that soil layers at a depth of about 0.3 times the length of the pile (i.e., 0.30L, where L = length of the pile) or greater has a negligible effect on the lateral deflection of the ACP. Based on the results of the lateral load test data of ACP, it is determined that the measured response of ACP to lateral load is somewhere in between the responses predicted using the linear and non-linear flexural stiffness of ACP. Further, reliable prediction of lateral displacement is not possible without knowing the accurate values of modulus of elasticity of pile material.
