摘要
光面爆破是指爆破后断面轮廓整齐、超挖和欠挖符合规定要求的爆破,从围岩稳定性着眼,愈是地质不良地段,更要采用光面爆破。文章以毛家坡隧道为例,概述了光面爆破技术的应用以及爆破参数、施工工艺和爆破效果。
Smooth blasting means that the profile is clear and both the over excavation and under excavation complies with the requirements specified. In view of stability of surrounding rock, it is more necessary to take smooth blasting for poor ground. This article briefly introduces the application of smooth blasting, blasting parameter and construction technology as well as blasting effect by taking Maojiapo tunnel for example.
