万州长江二桥南北两岸锚碇均采用复合式隧道锚碇结构。由于目前国内外悬索梁采用隧道锚碇结构仅有7座,复合式隧道锚碇结构在悬索桥上首次采用,锚碇洞室的大部分及锚塞体均位于三峡工程蓄水位+175.0以下,且距水涯线仅约18m,所处的地质条件相对较差,设计结构复杂,故其施工的技术含量较高,施工的难 Wanzhou Yangtze River Bridge North and South Anchorage are composite tunnel anchor 碇 structure. Since there are only seven anchor anchorage structures used in the existing domestic and international suspension bridges, the composite tunnel anchorage structure is first adopted on the suspension bridge. Most of the anchor anchorage cavities are located below +175.0 of the Three Gorges Project , And only about 18m from the water line, where the geological conditions are relatively poor, the design structure is complex, so the construction of high-tech, difficult construction
