| 摘 要： | 通过研究打桩公式法和应力波动法(如CASE法)，作者提出：用重锤或小型火箭筒一次冲击桩顶，用桩顶附近的检波器记录振波图和检测静、动位移，通过实测冲击能(总能量)转换系数、波动和振动各自消耗的能量等各物理量，测定计算单桩竖向承载力．利用振波图计算力(P)和位移(S)动态关系曲线、确定屈服点。并利用静载荷试验检验动测结果和确定动静PS曲线的相关常数，进而确定与承载力相应的沉降量。

| Abstract: | From studying methods of the pile-formula and stress-wave we take a new one of testing piles. The vibrations and waves figures are recorded, and dynamic and static displacement are measured by different transducers in neighborhood of piles top when pile is impacted by heavy hammer or micro-rocket, various energy are determined, and the bearable capability (support) of a pile is calculated. Same-time forces (P) and displacements (S) are calculated using wave figures, PS-curves are plotted. The yield point is determined in the figures. Furthermore Dynamic results are checked up by static tests results, relative constant of both yield are determined and sinking corresponding with supports are calculated. |
