| 摘 要： | 介绍了以雷管作为爆炸动力源,多孔装药爆炸法密实饱和砂的模型试验,实测了饱和砂土体在依次循环爆炸荷载作用下孔隙水压力的增长与消散过程,分析了孔隙水压力的变化规律。试验结果表明,孔隙水压力的增长与消散在沿深度及径向方向上的变化规律具有独特性。同时,对爆炸荷载在饱和砂土体内所引起的液化范围进行了分析,所得结论可为爆炸法处理饱和粉细砂地基的工程设计与理论研究提供参考。 |

| Abstract: | An indoor experiment on explosive compaction of saturated sand has been done.The changes of pore water pressure during blasting are measured and the laws of pore water pressure increment and dissipation are analyzed.It indicates that the processes of increment and dissipation of pore water pressure have particularity along the depth and radial.At the same time,the development rule of liquefaction under explosive loading is also analyzed;these conclusions obtained in the experiment,may provide some useful references for the engineering design and the theoretic study of explosive compaction for water-saturated granular foundation. |
| Keywords: | explosive compaction water-saturated sand pore water pressure model experiment |
