Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of drivingpile.
本文应用冲击机械系统动力学分析打桩过程中锤体与桩撞击时应力波的产生、传播以及该波对沉桩过程的影响。

The radius of plastic area, the maximum compress stress caused by drivingpile , and the pore water stress can be concluded by using the cavity expansion method and the effective stress theory.
The equipment is suitable for various underwater projects and can also be used as pile-driving ship, geology survey ship, charge ship for mud extrusion by explosion, drilling ship, and etc.
