摘　　要：沉管隧道沉放前所进行的基槽浚挖往往会对护岸结构、防汛设施及临近建(构)筑物的安全构成影响。因此,岸壁保护已成为沉管隧道设计关键技术之一。介绍了沉管隧道岸壁保护结构常用的结构形式以及国内外典型岸壁保护结构的设计经验。根据天津滨海新区海河沉管隧道的地质及场地特点,通过比较分析,建议采用格构式地下连续墙和搅拌桩重力式挡墙相结合的岸壁保护方案。Trench dredging would influence the safety of revetment structure,flood control facilities,and neighboring structures before tunnel immersion.Thus,quay wall protection has been one of critical technologies in design of immersed tunnel.This article describes the common types of quay wall protective structure in immersed tunnel,and design experience of typical quay wall protection structure both in China and abroad.According to the geological and site conditions of Haihe River Tunnel in Tianjin Binhai New Area,through comparative analysis,the lattice diaphragm wall and gravity retaining wall by mixing pile were recommended for quay wall protection scheme.
