摘要
为研究邻近地铁的道路与河道工程施工对既有线路影响,分析探索福州某邻近地铁的道路和河道工程施工项目.在分析工程项目基本概况、工程地质和水文地质的基础上,对新建工程的影响范围等级进行划分.根据影响等级的划分结果,对危险性较大的部位进行有限元模型的建立,以分析施工过程对既有线的影响,对既有线的结构位移、结构内力、净空收敛和轨道变形进行探索.最后,根据有限元分析结果,提出针对性的施工质量控制方案.通过有限元分析与对现场重点施工工序的分析研究,对重要环节的施工质量控制起到重要的作用.
Abstract
To study the impact of road and river engineering construction near the subway on existing lines,and to analyze and explore the road and river engineering construction project of a nearby subway in Fuzhou.Based on the analysis of the basic overview,engineering ge-ology,and hydrogeology of the engineering project,the impact range and level of the new construction project are classified.Based on the classification of impact levels,establish a finite element model for high-risk areas to analyze the impact of the construction process on the existing line,and explore the structural displacement,internal force,clearance convergence,and track deformation of the existing line.Fi-nally,based on the results of finite element analysis,a targeted construction quality control plan is proposed.Through finite element analy-sis and analysis of key construction processes on site,it plays an important role in controlling the construction quality of important links.
