爆炸压实饱和砂土的试验研究

An Experimental Research on Compaction of Saturated Sand Soil by Explosion

根据深层药包爆炸压实试验的实测资料,本文论述了饱和砂爆压过程的基本特性及其压实机理,总结了砂体内爆炸压力、质点振动加速度及超孔隙水压力的作用规律,同时提出了较合理的压实参数实用公式。

Based on the measured data of explosive tamping experiments with deep-level charges in sat urated sand soil, this paper discusses the basic characteristic and the mechanism of compaction by explo sion, summarizes the principles of explosive compression, particle acceleration and excess pore water pressure in sand soil, and also puts forward practical formulae of compactive parameters.
