摘　　要：随着黄河流域生态保护与高质量发展战略的深入实施,山东省迫切需要建设跨黄通道,解决公铁合建及其安全保障等难题。通过工程类比、模型与数值试验方法,结合周边环境保护和水文地质特点,对济南济泺路穿黄北延隧道工程设计关键技术以及风险控制措施进行总结分析,结果表明:通过协同疏散技术与综合通风体系,实现了盾构隧道断面集约化设计;采用“管片+非封闭内衬”计算模型、管片环间抗剪结构以及一体化防水的设计方法,提高了盾构隧道整体刚度与承载性能;计算了防淹门的可用关闭时间,为隧道防淹体系设计提供了理论依据;通过内部结构预制装配化设计,控制了隧道断面直径,加快了施工速度。经现场监测验证,建设风险安全可控,总体设计方案合理可行。With in⁃depth implementation on ecological protection and high⁃quality development strategy in the Yellow River Basin,the development of the crossing tunnel in Shandong Province has become urgent,requiring solutions for the challenges of rail⁃and⁃road combined construction and security guarantees.Through engineering analogy,modeling,and numerical testing methods,and considering the surrounding environmental protection and hydrogeological character⁃istics,key design techniques and risk control measures for the Jinan Jiluo Road Yellow River North Extension Tunnel had been summarized and analyzed.The results showed that the application of collaborative evacuation technology and a comprehensive ventilation system enabled a more efficient shield tunnel design.And the adoption of a“segment+non⁃closed lining”calculation model,segment inter⁃ring shear structure,and integrated waterproofing methods enhanced the overall stiffness and bearing capacity of the shield tunnel.And the available closing time of the anti⁃flooding door was calculated,which provided a theoretical basis for the design of the tunnel′santi⁃flooding system.Additionally,the use of prefabricated internal structures helped control the tunnel′s section diameter and accelerated construction speed.On⁃site monitoring confirmed that construction risks were manageable and the overall design was reasonable and feasible.
