摘要
隧道围岩开挖后的变形监测对于隧道的信息化施工有着重要的意义。改进的隧道围岩监测系统(TMS),采用各传递杆与岩体点接触,而不是通常采用的全孔灌浆接触方式,解决了全孔灌浆对监测结果的影响,特别是对软岩变形监测的影响。改进的TMS既能够保证各接触点的牢固,防止传递杆与岩体脱离,又可以最大程度地减小试验仪器本身对岩体位移结果的影响。该仪器精度高、操作性强、适应性强,通过在雪峰山隧道工程中的应用,表明效果良好。
The surrounding rock deformation monitoring after excavatio implications in the informationization construction. Improved tunnel monitoring system (TMS) , adopting point contact between the transmissio full contact by grouting, solves the influence to the monitoring results of wh the soft rock deformation monitoring. Improved TMS enables the point n of tunnel has an important surrounding rock deformation n bar and rock mass instead of ole hole grouting, especially for to contact firmly, avoids the transmission bar separating from rock mass, and minimizes the influence of instrument to the rock mass displacement results. The instrument is highly accurate, maneuverable and adaptable. A remarkable result was achieved in the monitoring work of tunneling in Xuefeng mountain.
