爆破技术在水利水电工程中的应用

On application of blasting technology to water and hydropower works

爆破是水利水电工程施工的主要手段之一,工程爆破技术是影响施工质量和进度的一个重要因素。本文对水利水电工程中的深孔台阶爆破、预裂与光面爆破、面板堆石坝级配料开采爆破、围堰爆破拆除、定向爆破筑坝、岩塞爆破、隧道掘进爆破等方面进行了介绍。

Blasting is one of the major approaches to construction of water and hydropower works and an important technical factor that has direct effect on engineering quality and progress.The paper introduces such techniques used in water and hydropower works as Deep - hole Bench Blasting,presplitting and perimeter blasting,material-quarrying blasting for rock - fill dam with face slab,cofferdam removal blasting,embankment directed blasting, chock blasting,Tunnel Driving Blasting and so on.
