摘要
隧道工程穿越不良地质时,围岩稳定性关乎施工与运营安全。以广西平容高速马鞍山隧道工程为背景,对比不同开挖方式,通过现场监测系统分析了新奥法施工下围岩的稳定性。结果表明,新奥法施工下隧道变形低于控制值,有效保障了围岩的稳定性,该研究成果可为类似工程提供借鉴。
The surrounding rock stability is related to the safety of construction and operation when tunnel engineering passes through unfavorable geology.Based on Ma'anshan Tunnel engineering on Pingrong Expressway in Guangxi,this paper compares different excavation methods and analyzes the stability of surrounding rock under the construction with new Austrian tunneling method through on-site monitoring system.The results show that the tunnel deformation under the construction with new Austrian tunneling method is lower than the control value,effectively guaranteeing the stability of the surrounding rock.The research results can provide reference for similar engineering.
