第三系砂泥岩隧道应力监控量测分析

Tertiary sand shale tunnel monitoring analysis of stress

监控量测是新奥法施工的重要组成部分,其可以简单直接的掌握隧道围岩变形和支护结构受力情况。通过依托牡绥线双丰隧道应力监测断面,详细的介绍了应力量测的原理、内容和监测数据的处理方法,以及得出第三系砂泥岩隧道最大跨处为围岩薄弱环节,在初期支护中要严格控制变形并采取加固措施等结论。通过监控量测能更好的调整施工方法和支护参数,确保施工安全,并为同类工程施工提供较大的参考价值。

Monitoring is an important part of the construction of new Austrian method,it can be simple and direct master the deformation of tunnel rock and supporting structure. Based on MUSUI line Shuang Feng tunnel stress monitoring cross section,it principle of force measurement are introduced simply,the content and the analysis of monitoring data deal processing. And it is concluded that the largest place of tertiary sand shale tunnel is the weak link of rock. To strictly control the deformation and primary support reinforcement measures. By monitoring can better adjust the construction method and support parameters,ensure the construction safety,and provide greater reference value for similar project construction.
