摘要
文章以通海隧道为依托,对隧道围岩与支护结构的内力进行监控量测,详细介绍了压力盒和应变计的埋设方法,对监控数据进行了分析,并给出通海隧道的施工建议。实践表明,监控结果能反应出隧道围岩与支护结构的稳定性情况,可有效指导隧道施工。
Relying on Tonghai Tunnel,the article conducted the measurement and monitoring on the internal force of tunnel's surrounding rock and supporting structure,introduced in detail the burying method of pressure box and strain gauge,analyzed the monitoring data,and proposed the construction recommendations of Tonghai Tunnel.The practice shewed that the monitoring results can reflect the stability situation of tunnel's surrounding rock and supporting structure,and can effectively guide the tunnel construction.
