| 摘 要： | 隧道锚具有环境扰动小、性价比高的特点,是悬索桥较理想的锚碇形式,但受地质条件以及人们对岩体性质的认识水平等条件的限制,目前在大跨径悬索桥中应用不多,相关文献也不多见。本文结合进行我国首座采用隧道锚的大跨径悬索桥—四渡河大桥隧道锚的设计及取得的成果,系统介绍了悬索桥隧道锚锚址的基本特点、锚体尺寸拟定、锚固系统选择以及数值分析、模型试验应注意的问题,便于隧道锚的进一步应用。

| Abstract: | Tunnel-Type Anchorage(TTA) is the reasonable types among the suspension bridge anchorage for its characteristics of less destroy to natural environment and high capability-investments ratio.The application of TTA is restricted by geological condition and the understanding of rock mass.Few TTA is used and related technical papers are published.In this paper,with the 1st TTA design of long span suspension bridge,Siduhe Bridge in China and the results of investigation,the basic geological characteristics of anchorage zone,the methods to decide TTA dimensions,the selection of anchorage system in TTA,the noticeable problems of numerical analysis and the model test of TTA are introduced.It can be referenced by other analogical design. |
