摘要
输电线路铁塔基础部分的施工周期及造价占整个工程的比例较大,介绍国内架空输电线路设计中几种常见基础型式及其适用性,对相同塔型不同基础型式进行技术经济分析,提出直线塔和转角塔优先选用掏挖基础,针对不同影响因素和基础型式的特点,结合工程实际情况,合理选择基础型式的建议。
The construction period and cost of transmission line tower foundation account for a large proportion of the whole project.This paper introduces several common foundation types in domestic overhead transmission line design and their applicability,makes technical and economic analysis on different foundation types of the same tower type,and puts forward that cut-out foundation is preferred for intermediate and corner tower.According to the characteristics of different influencing factors and foundation types,suggestions on selecting other reasonable foundation types in combination with the actual situation of the project.
