摘　　要：为改善航道环境,解决礁石覆盖砂土层的问题,采用爆破技术对回旋水域的礁石进行爆破。前期运用钻爆船进行钻孔,用炮孔法集中布置炸药,在礁石附近布置梅花孔,根据岩层强硬度的差异,进行钻孔加密,最后引爆并清除障碍,为码头基础施工建设做好基础工作。To improve the complicated channel environment and prevent the cover of reefs on sandy layer, the blasting technique is employed to blast the reefs in turning circle. Plum blossom hole is drilled on the reefs by drill-burst ship, and bombs are planted centrally in the holes using hole blasting method. Considering the existence of rocks with different hardness, some more holes are drilled if necessary. Finally, the bombs are detonated, and all the produced obstruction is eliminated for the foundation construction of port.
