摘要

介绍了高饱和度饱和土介质中结构和刚性边界反射爆炸波试验的背景，目的和方法。给出了爆炸载荷作用下饱和土中模型结构表面和刚性边界压力和动量的实测波形，并对实验结果进行了分析，得到了爆炸波在结构和刚性边界上的反射规律和反射系数。结构上的压力反射系数在0.4-1.4之间，刚性边界上的压力反射系数在1.0-2.0之间。

Abstract

In this paper, the experiment of blast wave reflection on structure and rigid obstacle in saturated soils with high degree of saturation are investigated and the testing background, the aim and the plan are introduced. According to recorded waveforms of stress and momentum, the experimental results are interpreted. The reflection laws of blast wave and coefficient reflection of substructure and rigid obstacle are obtained. The reflection coefficient of structure and rigid obstacle are form 0.4 to 1.0 and from 1.0 to 2.0 respectively.
