Bridge-tunnel transition structure between submerged floating tunnel (SFT) and deep-water suspension bridge
The invention discloses a bridge-tunnel transition structure between a submerged floating tunnel (SFT) and a deep-water suspension bridge, which is arranged on an artificial bridge-tunnel transition island. The artificial bridge-tunnel transition island comprises an internal part and an external part, wherein the bridge-tunnel transition structure, a side span transition pier, a suspension bridgeanchoring structure and an SFT shore connection structure are arranged on the internal part; the bridge-tunnel transition structure comprises an approach bridge, island ramp bridges, island surface roads and island slope tunnels; the approach bridge is linearly arranged and extends from the side span transition pier to the end of the span beyond the suspension bridge anchoring structure; the island ramp bridges adopt separated lines, achieve transition from the approach bridge to the island surface roads in a spirally downward manner, and achieve transition from the island surface roads to theapproach bridge in a spirally upward manner; longitudinal slopes are arranged on the island surface roads; the island slope tunnels are linearly arranged, and an open section, a grating section and aburied section are sequentially arranged on each island slope tunnel; and a cross section structure of the internal part comprises a lower island foundation and an upper upright island body. The artificial bridge-tunnel transition island structure disclosed by the invention has the advantage that smooth transition between a bridge surface and a tunnel pavement is achieved with a small length.
本发明公开了一种悬浮隧道与深水悬索桥之间的桥隧过渡转换结构，设置在桥隧转换人工岛上，该桥隧转换人工岛分为岛内部分与岛外部分；岛内部分设置桥隧过渡转换结构、边跨过渡墩、悬索桥锚锭结构和悬浮隧道接岸结构；桥隧过渡转换结构包括引桥、岛上匝道桥、岛上地面道路和岛上斜坡隧道；引桥为直线型布置且自边跨过渡墩至悬索桥锚碇结构外一跨；岛上匝道桥采用分离式线路，且以螺旋下行方式由引桥过渡到岛上地面道路，以螺旋上行的方式由岛上地面道路过渡到引桥；岛上地面道路设纵坡；岛上斜坡隧道为直线型布置并依次设置敞开段、光栅段、暗埋段；岛内部分的断面结构包括下部的岛基和上部的直立式岛体。本发明的桥隧转换人工岛结构，以较短的长度解决了桥面与隧道路面之间平缓过渡的问题。
