新建铁路隧道下穿既有运营隧道的设计与施工

Design and Construction of the New Railway Tunnel Under Crossing the Existing Operation Tunnel

为了加强各个地区之间的贸易往来,需要建设大型的铁路线路,以促进当地的经济发展。对于新建铁路隧道,由于很多地区铁路线路众多,交通往来繁忙,导致施工存在一定的难度,尤其是进行大角度、小距离的下穿既有运营隧道施工,对施工标准要求高,导致施工难度大。论文结合实际案例,分析具体的隧道施工要点。

In order to strengthen trade between different regions, large railway lines need to be built to promote local economic development.For the newly built railway tunnel, the railway line in many areas is numerous, traffic is busy, leading to the existence of some construction difficulties, especially for large angle, small distance tunnel construction beneath the existing operation tunnel, it has high requirements on the construction standard, leading to the construction difficulty. Combined with actual cases, this paper analyzes the specific construction points of the tunnel.
