| 摘 要： | 监控量测是新奥法施工中重要的组成部分,是工程动态设计与施工的依据。以玉磨铁路新平隧道为例,系统性的阐述了监控量测点的布设原则、监控量测数据的采集方法、频率、数据处理方法。对拱顶下沉、上台阶收敛、中台阶收敛和下台阶收敛随着时间变化规律进行分析,总结了上台阶收敛随着时间变化呈现出“加速变形-过度变形-趋于稳定”的3阶段变化规律,采用一次负指数方程预测上台阶收敛变形,为类似工程提供一定参考。

| Abstract: | Monitoring and measurement is an important part of New Austrian Tunneling Method(NATM)and the basis of dynamic design and construction.Taking Xinping Tunnel of Yumo Railway Station as an example,this paper systematically expounds the layout principle of monitoring and measuring points,the collection method of monitoring and measuring data,frequency,data processing method,and the disposal process of monitoring.Furthermore,the time-varying regularities of vault subsidence,upper step convergence,middle step convergence,and lower step convergence are analyzed.Finally,the three-stage variation regularities of upper step convergence with time are summarized,which are accelerated deformation,excessive deformation-tending,and stability.In addition,negative exponential equation is used to predict the convergent deformation of the upper step,providing some references for similar projects. |
