摘要
既有铁路涵洞接长或拆除新建已成为既有铁路扩能改造的一种特殊形式,为了保证既有铁路涵洞在接长或拆除新建施工过程中既有铁路运行安全及工程质量,合理的改造施工技术显得至关重要。论文以金温铁路2座涵洞改造施工为工程背景,通过对不同条件下涵洞改造施工案例的分析,并借鉴既有涵洞改造施工技术,对不同条件下涵洞改造施工技术做出了新的探讨。
In recent years,the existing railway culvert＇s extension or re-built has become a special form of revamping.Therefore,in order to ensure the existing railway operation safety and project quality when the existing railway culvert is extending or re-buiding.ln this paper, based on Jinwen expansion and renovation project, making a new discussion of construction technology for the culvert＇s modification.
