摘　　要：随着电气化铁路的快速发展,我国粤港澳大湾区规划建设的城际铁路首次采用了内径仅为7.7 m的单线盾构隧道建造技术,设计时速为200~250 km。本文提出一种满足低净空安装要求的弓形腕臂悬挂方案。Along with the rapid development of electrified railways,a single track shield tunnel with an inner diameter of 7.7 m only and a design speed of 200~250 km/h is adopted for the first time in the intercity railway planned for the Guangdong-Hong Kong-Macao Greater Bay Area in China.This paper presents a bow type cantilever suspension scheme to meet the requirements of low clearance installation.
