爆破挤淤技术在大连新机场深水围堰施工中的应用

Application of blasting and silting technology in deep water cofferdam construction of Dalian New Airport

大连新机场工程建设采用离岸填筑人工岛方案．药埋深等相关施工参数是深水围堰处理过程中的重点与难点进行爆破参数计算、施工工艺拟定，并进行施工效果分析。深水围堰采用爆破挤淤填石法施工。有效确定炸药药量以及炸，针对深水围堰爆破参数的问题，以B27围堰中点为研究对象．

Offshore filling artificial island program is adopted in the new airport project construction, whose deep water cofferdam is constructed using blasting crushing and silting method. Effective determination of the amount of explosives and explosives buried depth and other related construction parameters in deep water cofferdam treatment process is key and difficult. Taking the B27 cofferdam midpoint as the research object, this paper calculates the blasting parameters, proposes construction process, and analyses the construction effect.
