| 摘 要： | [目的] 随着输电线路的荷载越来越大,为了满足受力要求,铁塔与基础的连接型式广泛采用八地脚螺栓柔性塔座板,现有规范体系对该型式塔座板的相关计算方法尚无规定,故需对承载力进行研究。 [方法] 通过理论分析、数值模拟和真型试验等方式对八地脚螺栓柔性塔座板的承载力进行了研究。 [结果] 研究表明:受拉状态下底板应力呈非均匀分布状态。 [结论] 提出了全新的计算方法,对工程设计具有一定的借鉴意义。

| Abstract: | [Introduction] The transmission line load which applied on tower become lager and lager. In order to bearing the reaction, the flexible tower base plate with eight anchor bolts which used to connect the tower leg and foundation had been adopted commonly. But there isn′t any method to design this member in relative specification, so it is necessary to study the bearing capacity of base plate. [Method] This paper analyzed the bearing capacity by classical mechanics theory, finite element and full size experiment. [Result] Studies have shown that the stress of the base plate is unevenly distributed under tension force. [Conclusion] A new formula has been proposed. This formula has the reference value when design in project. |
