石家庄六线隧道与一般的铁路隧道不同，属于城市隧道工程，其规模与复杂程度在国内地下隧道工程中尚属首例。为确保隧道工程的顺利实施，同时也为今后类似隧道穿越城市工程提供借鉴与参考，在石家庄六线隧道设计、施工过程中，经过研究论证、理论计算、模拟分析、方案比选优化、现场试验和重难点技术科研攻关，成功解决了穿城入地连拱多跨超长距离隧道营业线施工技术难题，形成了松软地层超宽基坑围护技术、紧邻既有线带状基坑工程安全防护技术、连拱隧道下穿运营铁路安全防护技术、宽体隧道下穿城市主干道技术等一系列关键技术，以及客运专线铁路穿越城区修建技术重点科研成果。

The urban 6track tunnels (local 7track) in Shijiazhuang are different from other tunnels; their scale and complexity are unique in China. During the design and construction of the mentioned tunnels, a series of works, i.e. study demonstration, theoretical calculation, numerical analysis, construction scheme comparison and contrast, field testing and technical breakthrough, have been done so as to guarantee the safe construction of the tunnels. In the end, the safe construction of longdistance multiple arch tunnel is guaranteed; and a series of construction technologies, such as retaining of large foundation pit in soft strata, protection of beltshaped foundation pit adjacent to existing railway line, protection of multiple archtunnel crossing underneath running railway and construction of multiple archtunnel crossing underneath arterial road, and key research results of passengerdedicated railway crossing urban area are obtained.
