摘要
为了研究爆破对隧道近区支护结构的影响,以高速公路隧道为工程背景,通过监测围岩压力和隧道变形来反映爆破对支护时机的影响,利用应力释放法通过数值计算对隧道开挖过程以及支护情况进行仿真模拟。
In order to study the influence of blasting on the near area of tunnel,the tunnel of highway is taken as the engineering background.The influence of blasting on the lining time is analyzed by the stress and deformation of tunnel surrounding rock mass.The numerical calculation is used to simulate the excavation procedure and reinforcement situation in tunnel by the stress release method.
