A new method for testing pile by single-impact energy and P-S curve

By studying the pile-formula and stress-wave methods (e.g., CASE method), the authors propose a new method for testing piles using the single-impact energy and P-S curves. The vibration and wave figures are recorded, and the dynamic 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 (total energy), the consumed energy of wave motion and vibration and so on, the vertical bearing capacity for single pile is 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, the dynamic 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 pile body can be judged from the formation of P-S curves.

Study of Disconnectable Riser Turret Mooring System Applied in the South China Sea

- The present research has been made on the Disconnectable Riser Turret Mooring (DRTM) System which could be used in the oil fields of the South China Sea. The selection of the principal dimensions and their effect on the characteristics of the system have been discussed. By means of a computer program, the synthetical appraisement has been made in the ultimate mooring condition, disconnecting condition and reconnecting condition respectively. Mean-while, a comparison has been made between DRTM system and CALM system. It has been indicated that DRTM is suitable for the South China Sea and has technological and economical preponderance.
