环向聚能药包研制及其在建基面开挖中的应用

Proparation of the Annular Cumulative Charge and Its Application in Fundation Excavation Blasting

在水利水电工程中 ,水平建基面的开挖既严格又繁琐 ,为研究一种施工相对简单同时又满足规范要求的开挖方法 ,根据环向聚能药包的作用原理 ,研究了影响聚能药包破岩效果的因素 ,在此基础上研制出了切割型和射孔型两种不同环向聚能药包 。

In hydropower engineering,fundation excavation blasting is very strict and troublesome,for developing a simple implementation method to meet the code′s demands.This paper studies the cumulative charge principle and its influential factors.Thereafter two kinds of annular cumulative cartridge of cutting and embrasuring have been developed and produced,the blasting experiment has also been done.
