Dynamic Pile Testing Technology: Validation and Implementation

摘要: Driven piles are widely used as foundations to support buildings, bridges, and other structures. In 2007, American Association of State Highway Transportation Officials (AASHTO) has adopted Load Resistance Factor Design (LRFD) method for foundation design. The probability based LRFD approach affords the mathematical framework from which significant improvements on design quality control driven can be achieved. this research, reliability-based criteria developed acceptance-sampling analysis both static dynamic test methods with lognormal distribution characteristics. As a result, an optimum is suggested number load tests required measured capacities piles. Furthermore, research compiled large database pile set-up, FORM employed develop separate resistance factors reference (initial) capacity predicted set-up capacity. This report also provides Bayesian theory allow combining information calculation testing data improve process. Specifically, results utilized reduce uncertainties associated by updating corresponding factors. one-dimensional wave equation algorithm interpret High Strain Testing (HST) estimation shaft toe closed form solution obtained determining Smith damping factor soil resistance. Finally, set new wireless equipment (both hardware software) more efficient testing.
