| 摘 要： | 为控制爆破振动和爆破飞石,取得良好的爆破效果,基于HHT对爆破振速进行变换得到瞬时能量谱及钢筋混凝土移动方向综合分析爆破效果,并将通过ANSYS/LS-DYNA软件得到的模拟爆破效果与实际爆破效果对比,从而实现了对复杂环境下大型钢筋混凝土筏板基础爆破参数的优化。结果表明：孔间延时39/31 ms,排间延时101 ms, V型起爆的方案更合理。参数的优化方法和选取可为同类工程提供借鉴和参考。

| Abstract: | The form of surges aroused by throwing stone in three chamber blastings in Chenggaoshan project varies with topography, blasting parameters, the conditions of waters and shore. For this reason, they have different harms to the waters, shore and land structures around a blasting zone. The preventive measures to the surge should be worked out according to its strength and harm features. |
