大连湾海底沉管隧道防水与耐久性初步设计方案介绍

Preliminary Waterproofing and Durability Design for Immersed Tube Tunnel in Dalian Bay

针对我国北方城市大连海底沉管隧道初设阶段的防水与耐久性展开介绍,内容涵盖了工程建设背景与概况、混凝土结构自防水与耐久性设计、管节接头防水设计、节段接头防水设计,明挖隧道的全包防水设计、变形缝防水设计以及钢结构耐久性设计等方面,期望对我国北方海洋环境下的沉管隧道建设提供参考和借鉴。

The article introduces the first-stage design of waterproofing and durability for the immersed tube tunnel in Dalian, which locates in the north part of China. The introduction covers background and general situation of the project, concrete structural self-waterproofing and durability design, waterproofing design for pipe and segment joints, all-inclusive waterproofing design for open-cut tunnel, deformation joint waterproofing design and durability design of steel structure et cetera, hope it can be reference for construction of immersed tube tunnel under the marine environment of the north part of our country.
