| 摘 要： | 锚碇基础是悬索桥的关键受力部位,它的总体稳定性和受力状态直接影响到大桥的安全和长期使用的可靠性。当悬索桥设计桥面宽度一定时,若采用的隧道式锚碇截面变化情况下,锚塞体长度的确定除了与设计主缆缆力的数值大小有关外,还应考虑如何充分利用锚塞体围岩的力学性能。本文通过拟建的坝陵河悬索桥西岸隧道式锚碇锚塞体长度方案比选的数值模拟研究,获得锚塞体合理经济的长度,以供设计参考。

| Abstract: | Anchorage foundation is the key position of a suspension bridge,whose overall stability and bearing state directly influence the safety and long-term reliability of the bridge.With fixed width of bridge deck and changing section of tunnel-type anchorage,the decision of concrete plug length must consider how to make the best of the mechanical performance of surrounding rock as well as the design value of tensile force in main cables.Rational and economical length of anchoring concrete-plug is obtained by numerical simulation on scheme comparison between two kinds of concrete-plug length of west tunnel-type anchorage of planned Balinghe Suspension Bridge to provide reference for design. |

| Keywords: | tunnel-type anchorage anchoring concrete-plug scheme comparison |
