摘要
通过对DL/T 5219—2005架空送电线路基础设计技术规定及GB 50017—2003钢结构设计规范中关于对地脚螺栓(锚栓)设计规定的分析,考虑了水平剪力对地脚螺栓设计的影响。对《架空送电线路基础设计技术规定》中地脚螺栓的设计方法增设抗剪构造;在无抗剪措施情况下,对地脚螺栓施加预拉力,通过塔脚板与混凝土基础间产生的磨擦力来平衡水平剪力。
By the analysis of regulations in Technical code for designing transmission line foundation (DL/T 5219 - 2005) and Code for design of steel structures (GB 50017 - 2003) concerning the bottom bolt, the influence of foundation's horizontal load on bottom bolt was considered. The formula of Technical code for designing transmission line foundation can be used when having bond of shearing. When without bond of shearing, the bottom bolt must be exerted pretension.
