厦门港招银港区7^#泊位抛石基床爆夯工艺

Explosive Blasting Technology on Throwing Rock Base-bed Testing Section at Berth 7thWharf Engineering

厦门港招银港区7#泊位建设过程中基床爆夯拟通过试夯,以确定基床爆夯参数。试夯主要综合考虑了水流、周围建筑物及炸药性能等因素,通过计算数据和试验数据比较分析,寻找适合爆夯施工的单包炸药配重、炸药单包重量、药包布设网格间距及爆夯遍数等参数,最终完成该泊位抛石基床爆夯施工。

The parameters of explosive compaction for base-bed during the construction of Berth 7tth wharf Engineering, Harbour Area of China Merchants Bank,Xiamen Port, are determined through test explosive compact. The factors such as water flow, ambient structure and performance of powder are mainly and comprehensively considered in the test. The parameters of counterweight, weight of each explosion bag,the gird spacing and the times of explosive compaction suitable for explosive compaction construction are seek by the comparison and analysis of test data.
