复杂条件下的码头基槽炸礁质量控制

The Quality Control of Foundation Ditch Blasting in Complex Conditions

厦门海沧7#泊位基槽水下炸礁区域紧邻航道、码头趸船、油罐和民房等重要的建筑物,施工条件复杂,必须在有效控制爆破地震效应影响的前提下确保码头基槽炸礁质量。根据第一阶段的爆破效果分析确定了影响炸礁质量的因素,有针对性的在后续施工中采用控制措施,改进工艺方法,使爆破效果得到改善,保证了基槽炸礁质量。

The engineering of the 7th quay foundation ditch blsting in Haicang of Xiamen is nearby the waterway, oilcans and village, so the construction conditions are very complex. In the precondition of efficacious control the influence of earthquake, the blasting quality of the ditch must be ensured. This paper analyses the factors of influencing the blasting quality on the basis of the blasting effect in the first phase, and adopts special control measures to improve the blasting effect and the construction quality.
