悬索桥隧道锚由于利用了岩体的抗剪强度，工程规模一般远小于相同承载力的重力式锚，因此具有巨大优势。文中从岩体力学的角度出发，探讨隧道锚抗拉承载力公式，为工程前期阶段的隧道锚设计提供借鉴依据。
懸索橋隧道錨由于利用瞭巖體的抗剪彊度，工程規模一般遠小于相同承載力的重力式錨，因此具有巨大優勢。文中從巖體力學的角度齣髮，探討隧道錨抗拉承載力公式，為工程前期階段的隧道錨設計提供藉鑒依據。

Compared with gravity anchorage,the rock mass shearing strength is used so that the engi-neering scale of tunnel anchorage for suspension bridge is generally lower and under the same bearing capacity conditions.Tunnel anchorage has been showed great advantages.The tensile bearing capacity formula based on rock mass mechanics is discussed in this article.Some useful conclusions are got, this may provide guidance on the early stage of tunnel anchorage design.
