Suspension bridge gravity type anchorage and tunnel combined structure and co-construction method thereof
The invention discloses a suspension bridge gravity type anchorage and tunnel combined structure and a co-construction method thereof, and relates to the technical field of bridge engineering. The co-construction method comprises the steps: excavating a foundation pit in a mountain; then, pouring an anchorage foundation with a tunnel into the foundation pit; communicating the tunnel in the anchorage foundation with the tunnel in the mountain; and finally, pouring an anchor body on the foundation. The anchor body comprises an anchor block which is located above the foundation and used for anchoring a main cable strand, a splay cable saddle buttress which is supported at the front end of the anchorage foundation and used for supporting a splay cable saddle structure, and an anchor chamber which is located between the anchor block and the splay cable saddle buttress and used for protecting a main cable structure. According to the method, the tunnel and the anchorage are built together, and compared with a conventional gravity type anchorage building scheme, the foundation excavation amount is saved, and disturbance to the environment in the construction process is relatively small.
本发明公开了一种悬索桥重力式锚碇与隧道组合结构及其共建方法，涉及桥梁工程技术领域。其共建方法包括：在山体里开挖基坑；然后向基坑里浇筑带有隧道的锚碇基础；将锚碇基础中的隧道于山体里的隧道连通；最后在基础上浇筑锚体。所述锚体包括：位于基础上方用于锚固主缆索股的锚块、支撑于锚碇基础前端用于支承散索鞍结构的散索鞍支墩、位于锚块与散索鞍支墩之间用于保护主缆结构的锚室。本发明中将隧道与锚碇合建在一起，相较于常规重力式锚碇的建造方案，本发明节省了地基开挖量且施工过程中对环境的扰动相对较小。
