堤下爆炸法处理淤泥地基新工艺的理论、实验及工程应用(Ⅱ)桩对桩间抛石棱体下爆炸挤淤的动力响应

The Theory, Experiment and Engineering Applications of the Under Embankment Explosion Method for Sediment Removal (Ⅱ)The Dynamic Response of Piles Due to Under Embankment Explosive for Sediment Removal

本文是堤下爆炸法处理淤泥地基新工艺的研究及应用的第二部分，着重介绍该工艺应用于桩间棱体的挤淤时，爆炸冲击波和淤泥、石块运动对桩的作用。计算和检测表明，桩体的安全是可以得到保证的。

Based on model experiments and site investigation, the authors have studied how to handle soft foundation between piles by blasting, which has strong background of engineering. The method to handle soft foundation between piles by blasting is reliable, safe and easy to operate, with better strengthening effects.
