大跨度隧道弱爆破开挖对山体产生振动,影响附近民房安全和山体滑坡落石,采取振动监测确定弱爆破振动影响力,有利于进一步采取防护措施和改进施工工艺、调整爆破方案。
The weak-blast excavation of long-span tunnels will produce vibration to the mountain and affect the safety of nearby houses and landslides on the landslide. Vibration monitoring will be used to determine the influence of weak blasting vibration, which is conducive to adopting further protective measures and improving the construction technology to adjust the blasting schemes.
