摘　　要：对中央大道海河隧道工程沉管施工关键技术进行了分析研究,阐述了沉管接头抗震分析、管段预制及沉放、干坞稳定性分析以及护岸结构稳定性分析等关键技术,为我国北方地区、高震区修建类似工程积累经验。Upon the basis of analyzing and studying the key techniques for the construction of the immersed tubes for the Haihe River Tunnel Project under the Central Avenue of Tianjin, such key techniques for the project as the anti-seismic analysis of the joints of the immersed pipes,the pre-casting and sinking of the pipe segments, the stability analysis of the dry dock, as well as the stability analysis of the protective banks, are expounded in the paper. The paper helps accumulate experience for building similar projects in northern regions and high-seismic districts of our country.
