红水河桥梁角滩航道整治水下爆破工程

The Underwater Blasting Project for Dredging the Channel of Angle Shoal Under Hongshuihe Bridge

针对桥梁角滩水下爆破周边环境复杂、爆破区周边处于来宾公路大桥的特别环境,介绍爆破施工中采用的方法。该工程爆破设计合理,施工管理科学,爆破效果较好。近距离水下钻孔爆破地震效应对公路大桥安全影响的专题研究,针对性强,实用价值高,取得创新成果,应用前景广阔。

In light of the environmental complex surrounded the underwater blasting area of the angle shoal under the bridge, as well as the special conditions that the blasting area locates near Laibin Highway Bridge, this paper introduces the approaches adopted in blasting construction. This blasting project is with reasonable design, scientific construction management and good blasting effect. The monographic study on the influence of earthquake effect of short-distance underwater boring and blasting to the safety of highway bridges is of clear aim and high practical value with innovated achievements and wide prospect of application. 
