The process of impact hammer drilling is characterized by high non-linearity and large deformation and damage. 冲击锤(IH)的钻进过程是一个高度非线性、大变形、破坏的过程。
Pile-forming is reliable by using impact hammer, adding parabolic fill and building dikes as the protective wall. 采用冲击锥形锤,添加抛填料,筑暗筑堤作为护壁,可以实现再溶洞泥砂中可靠成桩。
The result shows that the bounces of anvil and bit lead to the many times of percussion of the impact hammer drilling system. 结果表明,由于砧子及钎头的反弹,导致冲击锤(IH)钻凿系统发生多次冲击现象。
The optimum principle and method hereof is of general sense to the vibration impact hammer. 给出的优化原理与方法,对振动冲击锤(IH)具有普遍意义。
