摘要(Abstract):
针对水下钻孔爆破危害防护问题,通过海边浅层水中钻孔爆破试验,实测得到了水中冲击波波形曲线及压力数据,对现在比较流行的抑制水下爆破负面效应的两种手段——延时起爆和气泡帷幕方法进行了验证与探讨。试验表明,选择合适的延时起爆能使总爆炸能量在时间上合理分布,而气泡帷幕手段对特定频率的冲击波有良好的削弱效果,为进一步的研究积累了很多有益的经验。
Regarding the preventative protection from blasting harm in underwater drilling,waveform curves and pressure data of shock wave were practically measured through testing of underwater drilling blasting in shallows at seashore,with the two popularly used measures,titled millisecond blasting and bubble curtain,for weakening the negative effect being discussed and verified. The test results showed that proper employment of millisecond blasting could enable the total explosion energy to disperse rationally according to time,while bubble curtain could only show its weakening affect on some shock waves of specific frequencies. The paper presented plenty of valuable experience for further study.
