摘要
随着我国铁路建设事业的迅猛发展,隧道开挖作业所面临的环境越来越复杂。重庆铁路枢纽规模宏大,穿越城市繁华区,尤以新红岩隧道埋深浅,上部楼房林立、人口密集,重要建(构)筑物和精密设备保护点较多。如何控制隧道施工对周边环境及邻近居民的影响是本工程重难点所在。文章针对非爆破开挖技术方案进行比选并结合隧道工程实际情况最终选择了悬臂式掘进机方案。
With the rapid development of domestic railway construction, the tunnel construction is facing more and more complicated environments. The Chongqing Railway Terminal crosses busy urban areas in a broad scale. As a key component of the terminal, the Xinhongyan Tunnel, a shallow buried tunnel, features buildings and a dense population above, including quite a few important buildings and precision machinery that required protection. How to control and minimize the effects on environment and residents induced by tunnel construction has become a prominent topic that needs to be addressed urgently. This paper discusses the selection of non-blasting excavation options. Based on the tunnel features, the option with boom-type roadheader was finally determined.
