摘要
隧道工程施工监控与预警是保障安全、优化设计、指导施工的重要手段,监控技术和预警方法标志着隧道的施工水平和质量,结合北京密云县密兴路火郎峪隧道施工监控实践,建立了岩质公路隧道施工监控资料分析与预警系统,得到了隧道爆破施工参数、振动波传播规律、应力应变规律和隧道施工期间的围岩收敛与拱顶沉降规律,提出了隧道施工的合理组织方案和施工措施。
Construction monitoring and early warning in tunnel engineering are important means to guarantee the safety,optimize design and guide construction.Monitoring technologies and warning methods of construction mark the level and quality of tunnel construction.With the practice of construction monitoring during the construction of Huolangyu tunnel in Mixing road reconstruction project,the authors establish a rock road tunnel monitoring data analysis and early warning system,find the laws of tunnel blasting parameters,vibration wave propagation,stress and strain,surrounding convergence and vault settlement in construction,and propose some reasonable organization programs and construction measures of the tunnel construction.
