- 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.
