红土山隧道断层破碎带施工中监控量测的应用

摘要

Tunnel monitoring measurement ,as an important guarantee of tunnel construction safety ,has been highly paid attention and widely used in highway tunnel construction in China .In this paper ,taking the monitoring measurement of Hongtu Mountain Tunnel(located in highway from Yushu to Qumarleb ) as an ex‐ample ,data of tunnel vault crow n settlement is analyzed ,w hich plays an important role in tunnel collapse pre‐venting and rock wall and support adjusting .In sum ,tunnel monitoring measurement is necessary in tunnel construction .%随着我国公路隧道施工安全性受到越来越高的重视。监控量测工作作为隧道安全施工的一种重要保障，在隧道施工中进行应用已非常重要。本文以玉曲线红土山隧道监控量测为例，通过对红土山隧道断层破碎带区域内的三个拱顶下沉量测断面的数据进行整理和分析，其结果在避免隧道拱顶坍塌、调整围岩支护参数等方面具有非常重要的作用。因此，在隧道施工中需要加强监控量测工作是非常必要的。
