深埋地下空洞的爆炸夯实技术

Compaction for Underground Deep Cavity by Blasting

叙述了在民用机场建设中应用爆炸 强夯技术处理深埋地下空洞的工程方法,工程中采用深部、浅部集中药包相结合和顺序起爆方法,爆炸夯实后采用高能级强夯进行处理。检测结果表明,爆破 强夯法使地下20余m深处的空洞得以夯实,达到了设计要求的密实程度,取得了良好的工程效果。

The engineering method of applying the blasting to compact the cavity under a civil airport is presented. A sequential detonating method and combining deep and shallow concentrated cartridge are adopted, and a high-energy-level compaction is adopted after the blasting compaction. The measurement results show that the method compacts the underground cavity in a depth of over 20 m, to designed compactness.
