爆破挤淤处理深厚淤泥在蚂蚁岛造船厂围堤项目中的应用

Application of Blasting Compaction Treatment in Deep Silt of Retaining Dyke Project of Ant Island Shipyard

结合土力学与爆炸力学理论,分析处理深厚淤泥爆破挤淤的机理。针对舟山市蚂蚁岛造船厂围堤工程运用爆破挤淤处理深厚淤泥的情况,介绍该工程的爆破技术参数的选取、施工工艺的控制以及钻孔检验、物探检验等,检验结果显示抛石体与淤泥的混合层均小于1.5 m,很好地达到了设计要求。

Combined with soil mechanics and mechanics of explosion theories, the mechanism of deep silt treatment by blas- ting was analyzed. In terms of the circumstances of blasting compaction treatment on deep silt for the retaining dyke project of Ant island shipyard, the authors discussed in detail about the blasting parameter selection, construction control, borehole test and ge- ophysical test etc. The results showed that the mixed layer of stone-filled and mud is less than 1.5 meters, which meets the de- sign requirements well.
