摘要
文章介绍了张石高速北口隧道软弱破碎围岩段支护方案的优化过程。通过采用现场监控量测法对优化方案进行动态监测,其结果与数值模拟结论基本吻合,表明隧道处于稳定状态,施工与支护方案合理。
The article introduces the optimizing process of a support plan,which is designed for the soft breaking adjoining rock on north tube of Zhangshi highway tunnel.With the ambulatory monitoring on this plan by on-the-spot monitor measuring,the data turned out basically the same with the result of numerical modeling,which shows that the tunnel is stable and also,the construction and support plan is rational.
