Abstract : A vibratory pile driver has the capability of substantially decreasing pile installation time compared to the impact driven pile in certain soil conditions. Despite the increased interest in the use of this type of driver for driving and extraction, no reliable method exists for estimating the pile's bearing capacity. Field tests were conducted in San Diego, California in an effort to compare bearing capacity calculations for vibratory driven pile based on theoretical static analysis, empirical analysis using cone penetrometer test data, and dynamic driving resistance. Data obtained while driving instrumented pile is compared with predictions obtained from an analytical model. This preliminary model simulated the vibratory drive-pile-soil system. This technical note evaluates the influence of various parameters on the vibratory pile driving process.
