［摘要］由于現(xiàn)行抗浮錨桿設(shè)計(jì)的執(zhí)行標(biāo)準(zhǔn)不統(tǒng)一、不全面，從抗浮錨桿傳力特性出發(fā)，分析了筋體材料、灌漿材料、鉆孔方法對(duì)錨桿承載力及耐久性壽命的影響。就常用的全長(zhǎng)粘結(jié)型抗浮錨桿的設(shè)計(jì)提出應(yīng)注意的四個(gè)關(guān)鍵點(diǎn)：合理設(shè)計(jì)錨桿長(zhǎng)度，合理布置錨桿，重視耐久性設(shè)計(jì)，注意桿體在結(jié)構(gòu)主體內(nèi)的錨固節(jié)點(diǎn)設(shè)計(jì)。研究成果對(duì)確保錨桿設(shè)計(jì)安全、增加其耐久性壽命有一定的參考意義。

Abstract: Because the current executive standards of the anti-floating anchor design are not uniform and comprehensive, starting from the force transmission characteristics of anti-floating anchor, the influence of the reinforced material, grouting materials and drilling methods on the bearing capacity and durability life of the anchor were analyzed. The following four key points were put forward for the design of the most common fully grouted anti-floating anchor：reasonable design of the length of the anchor，reasonable arrange of the anchor, emphasis on durability design, and attention to the details of the anchoring node of the rod in the main structure design. The research results have certain reference significance for ensuring the safety of anchor design and increasing its durability life.  

Keywords:fully grouted anti-floating anchor； length of the anchor; bearing capacity； affecting factor； durability design
