输电铁塔与基础常见的连接方式为地脚螺栓连接和插入角钢连接,此文从技术、经济、安全和效率4个方面对两种连接方式进行对比分析。结果表明,插入角钢连接基础受力更优且在经济性上具有微弱优势,而地脚螺栓连接具有适用范围广、技术可靠、便于抢修、安全风险低和效率高等优势。由此可见,地脚螺栓连接优势明显,更适合工程应用。

The common connection modes between power transmission towers and foundations are bay bolt connection and inserted angle steel connection.The paper makes a comparative analysis on the two connection modes from four aspects of technology,economy,safety,efficiency.The results show that the inserted angle steel connection has slim economic advantage and the foundation is better stressed in this connection mode,while the bay bolt connection has the advantages of wide application scope,reliability,easiness in emergency repairing,low safety risk and high efficiency.It can be seen that the bay bolt connection has obvious advantages and is more suitable for engineering application.
