摘要
结合沪昆铁路客运专线背阴坡隧道偏压进洞施工,介绍了浅埋偏压大断面隧道半明半暗进洞施工特点、施工顺序以及施工过程中采取的措施。与传统先反压回填再进洞施工方法比较,半明半暗预支护施工工艺具有安全、稳定、快速进洞施工的优点,对类似浅埋偏压隧道施工具有一定的指导意义。
Combined with the shady slope tunnel biased entering into the hole construction on Shanghai-Kunming Railway Passenger Dedicated Line, the paper introduces the characteristics, sequence and measures of shallow buried large section semi-dark entering tunnel with biased pressure. Compared with the traditional anti-pressure backfill method, the semi-dark support construction boast the advantages of security, stability and fast entering etc. which can provide examples for similar construction
