大跨度矿山法地铁隧道快速施工技术

Subway Tunnel Rapid Construction Technology with Large-span Mining Method

地铁建设已经成为了当前我国城市发展建设中主要的建设项目,在地铁施工中,部分城市由于城市地质条件的复杂性,常需要使用大跨度矿山法进行地铁隧道的开挖施工。在大跨度矿山法地铁隧道快速施工中,需要使用支护对隧道进行保护,以保障施工安全性,避免施工危险问题的发生。本文对大跨度矿山法地铁隧道快速施工技术的技术原理进行剖析,并通过实际工程案例,对快速施工技术的技术难点及要点进行研究,以推动我国城市地铁建设发展。

Subway construction has become the main construction project in the current urban development and construction in China.In the construction of subways,due to the complexity of urban geological conditions,large-span mining methods are often used to excavate subway tunnels.In the rapid construction of a large-span subway tunnel,it is necessary to use support to protect the tunnel to ensure the safety of construction and avoid the occurrence of dangerous problems in construction.This paper analyzes the technical principles of the rapid construction technology of large-span subway tunnels,and studies the technical difficulties and points of rapid construction technology through actual engineering cases to promote the development of urban subway construction in China.
