摘要
深宽双壁路堑洞室爆破开挖边坡保护是爆破工程中的难题。根据影响路堑边坡稳定的主要因素，提出洞室爆破药室布置的新型式、装药量计算公式及长矩形不耦合装药结构等爆破新技术。这些技术通过太（原）旧（关）高速公路等工程的应用，效果良好。
Slope protection of deep and wide road cut of two side by chamber blasting is a complicated problem in blasting engineering.This paper analyzes the main influential factors of stable slope,and proposes a new style of chamber arrangement,calculating formulae if charge quantity and long rectangular decouple charge construction in chamber blasting.The technique have achieved good results in the road cut engineering of Taijiu highway.
