The Theory, Experiment and Engineering Application of the Under Embankment Explosion Method for Sediment Removal (Ⅰ)Theory and Experimental Research of Under Embankment Explosion Method for Sediment Removal

在淤泥质海岸建造高桩码头，通常在开挖基槽后沉桩再抛石形成棱体。基槽中的回淤淤泥很难清除，为此研制了堤下爆炸挤淤新工艺。本文是关于该新工艺的理论、实验及工程应用的一个总结，分两部分，第一部分着重介绍挤淤机理、装药工艺、模型律及药量公式等。研究及应用表明，这种新工艺与先前我们研制成功的爆夯法及爆填法一起，构成了较为完整的工艺系列。

In this paper, the model law and the formulation of the explosive charge of under embankment explosion for sediment removal are presented. The geometric similarity is established based on dimentional analyses and experiments. The experiment shows that the explosive addition formula derived from the model can be used in engineering practice.
