摘要
施工监测是隧道工程施工中不可缺少的工作之一,文章以甘肃省陇南市某铁路隧道施工监测为例,通过对拱顶下沉和净空收敛监测结果的整理与回归分析,分析了围岩变形过程及其发展规律,得出了初始变形阶段、急剧增长阶段和基本稳定阶段的时间节点,为该隧道施工及支护提供了基础数据,保证了施工过程的安全性与经济性,也能为同类型隧道施工提供一定的借鉴。
Construction monitoring is one of the indispensable tasks in tunnel engineering construction.Taking the construction monitoring of a railway tunnel in Longnan City,Gansu Province as an example,this paper analyzes the deformation process and development law of the surrounding rock,summarizes the time nodes of the initial deformation stage,the rapid growth stage and the basic stability stage,which provides basic data for the construction and support of the tunnel,ensures the safety and economy of the construction process,and will also provide certain references for the construction of the same type of tunnel.
