文章主要介绍了在东北某引水隧洞穿越既有铁路线工程中的施工期监控量测工作。针对该工程洞室埋深浅、所处地层地质情况复杂等工程特点,文章作者和相关团队认真选取监测项目,设计监测方式、方法,对围岩和支护、衬砌的力学行为以及它们之间的力学关系进行量测和观察,并对其稳定性进行了评价,在工程实践中取得了较好的效果。
This paper mainly introduces the monitoring and measuring work in the construction period of a diversion tunnel in the northeast through the existing railway line. In view of the engineering features such as the shallow buried depth of the engineering cavern and the complicated geological conditions of the strata, the article authors and relevant teams carefully selected monitoring items, designed monitoring methods and methods, and analyzed the mechanical behaviors of the surrounding rock and the support and lining as well as their Mechanics relationship between the measurement and observation, and its stability were evaluated in engineering practice has achieved good results.
