低净空盾构隧道内接触网悬挂方案研究

Study on Suspension Scheme of OCS in Low Clearance Shield Tunnel

目前160 km/h城际铁路、市域铁路中大多采用低净空盾构隧道,这类工程具有盾构隧道长、净空低的特点,接触网悬挂方案需从技术成熟度、环境适应性、施工安装、运营维护、经济性等方面进行技术、经济综合比选,以确定最合理的悬挂方案。

At present,most of the intercity and municipal 160 km/h railways use low clearance shield tunnels.This kind of project has the characteristics of long shield tunnel and low headroom.The OCS scheme should be comprehensively compared and selected from the aspects of technical maturity,environmental adaptability,construction and installation,operation and maintenance,and economy,so as to determine the most reasonable suspension scheme.
