近年来,随着我国铁路、公路及市政建设事业的高速发展,越来越多的隧道工程投入建设。由于地质条件的限制及地下空间的综合开发利用,在工程中不可避免地产生近距离交叉隧道。鉴于新建隧道施工会对既有隧道造成不利影响,同时也增加了新建隧道施工的难度,结合某城市隧道上跨厦深铁路隧道的工程设计实例,着重对比分析新建隧道两种施工方案,探讨交叉隧道段加固方案以及监控量测方案,对近距离隧道施工具有一定的指导意义。
In recent years, with the rapid development of China’s railways, highways and municipal construction, more and more tunneling projects have been put into construction. Due to the limitation of geological conditions and the comprehensive development and utilization of underground space, inevitable cross-over tunneling will occur in the project. In view of the new tunnel construction will have an adverse impact on the existing tunnel, but also increased the difficulty of the new tunnel construction, combined with a city tunnel across the Xiashen railway tunnel engineering design examples, focusing on comparative analysis of two new tunnel construction program to explore the intersection The reinforcement scheme of tunnel section and the monitoring measurement scheme have certain guiding significance for the construction of short-distance tunnel.
