深宽双壁路堑洞室爆破开挖减震技术

The technique of decreasing Vibration of deep and Wide road cut of two side by chamber blasting

文中提出的洞室爆破药室布置新型式、装药量计算公式及长拒形不耦合装药结构等综合减震爆破技术，解决了深宽双壁路堑洞室爆破开挖工程中的减震难题。这些技术通过太（原）旧（关）高速公路等工程的应用，效果良好。

The new style of chamber arrargement, calculating farmulas and fang rectangular decouplechange construction to decreasing blasting vibration are mentioned in this paper. These techniquesresolve cushion problems in chamber blasting engineering of deep and wide road cut Of two-side.The technique has achieved good results in the road cut engrneering of Taijiu highway.
