A new method for testing pile by single-impact energy and P-S curve
摘要
Abstract
By studying the pile-formula and stress-wave methods (e.g., CASE method), the authors propose a new method fortesting piles using the single-impact energy and P-S curves. The vibration and wave figures are recorded, and thedynamic and static displacements are measured by different transducers near the top of piles when the pile is impacted by a heavy hammer or micro-rocket. By observing the transformation coefficient of driving energy (totalenergy), the consumed energy of wave motion and vibration and so on, the vertical bearing capacity for single pileis measured and calculated. Then, using the vibration wave diagram, the dynamic relation curves between the force(P) and the displacement (S) is calculated and the yield points are determined. Using the static-loading test, thedynamic results are checked and the relative constants of dynamic-static P-S curves are determined. Then the subsidence quantity corresponding to the bearing capacity is determined. Moreover, the shaped quality of the pilebody can be judged from the formation of P-S curves.关键词
