摘要
由于现行抗浮锚杆设计的执行标准不统一、不全面,从抗浮锚杆传力特性出发,分析了筋体材料、灌浆材料、钻孔方法对锚杆承载力及耐久性寿命的影响。就常用的全长粘结型抗浮锚杆的设计提出应注意的四个关键点:合理设计锚杆长度,合理布置锚杆,重视耐久性设计,注意杆体在结构主体内的锚固节点设计。研究成果对确保锚杆设计安全、增加其耐久性寿命有一定的参考意义。
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.
