摘要
为研究复合地层条件下超大断面浅埋暗挖隧道曲线顶管施工参数分布规律,以港珠澳大桥珠海连接线关键控制性工程——拱北隧道为依托,基于拱北隧道暗挖段管幕工程施工现场实测数据,采用统计分析、线性拟合等方法,总结了现场曲线管幕工程主要施工参数分布规律,建立了不同计算方法的线性拟合函数,在此基础上,提出了适用于估算珠海地区海陆相富水复杂地层顶管施工迎面阻力计算公式。
In order to study the distribution law of construction parameters in curved pipe-jacking with super-large section shallow underground excavation tunnel in complex strata,based on the fact data of Gongbei Tunnel pipe roof project which is the key control project of the Access Road on Zhuhai Side of Hong Kong-Zhuhai-Macao bridge,through statistical analysis,linear fitting and other method,the distribution laws of construction parameters incurved pipe-jacking are summarized,different linear functions are built with different calculation ways.Based the study results,the calculation formula is proposed to estimate penetration force in curve pipe jacking,which is applied in Zhuhai marine continental complex strata.
