文章结合厦榕高速巫邦隧道的工程概况和公路隧道监控量测方案,介绍了隧道监控量测的内容与方法,并在现场监控量测的基础上,采用回归方法对围岩变形情况进行预测。预测结果表明:拱项下沉值为周边位移的2倍,围岩初期支护周边位移和拱顶下沉在开挖45d后保持稳定。该结论可用来有效地指导隧道施工。
This paper introduces the project overview of Wubang tunnel in Xiarong highway and the monitoring measurement of the highway tunnel.It is shown that the vault subsidence value is twice as much as the periphery displacement,amd in the early period of surrounding rocks,they can keep stable after 45 days' excavation.This result can guide the tunnel con -struction.
