Investigation of Explosions for Water-saturated Granular Ground Improvement
QU Jun-tong · Underground Space · 2005
In order to study the effects of explosions for water-saturated granular ground improvement, an investigation in site is carried out in the reclamation by bumping filling of one dock. The process of increment and dissipation of pore water pressure, ground surface settlement, contact sensor values are measured, some specific conclusions such as laws of increment and dissipation of pore water pressure are obtained. To adopt the cyclic explosion mode is favorable to ground improvement, densification of granular ground has progressed to the state of medium compaction by explosion, etc. are presented in this paper. All these conclusions and investigation provide valuable references for design and the theoretical study of explosions for ground improvement.
