[Introduction] Tower weight and foundation concrete quantity are important indexes in transmission line engineering. By comparing the tower weight and foundation concrete quantity of 10 mm, 15 mm, 20 mm, 30 mm and 40 mm ice area typical towers used in YunGui interconnection channel project, this paper explores the influence of ice area on tower weight and foundation concrete quantity. [Method] The components of the tower were analyzed and the relationship between each component and the total weight of the tower was fully understood; Through the comparison and analysis of tower weight and foundation concrete quantity in different ice areas, the relationship between different ice areas and tower weight and foundation concrete quantity was studied. [Result] The analysis shows that for the tension tower, the proportion of the tower body below the variable slope to the total tower weight is the largest; for the tangent tower, the cross arm, the tower body above the variable slope and the tower body below the variable slope all account for a large proportion of the total tower weight; the influence of ice area on the weight of tangent tower is greater than that of tension tower, and the increase of tower weight in 30 mm ice area is the largest; the influence of ice area on the concrete content of tension tower foundation is greater than that of tangent tower, and the increase of concrete content of tower foundation in 30 mm ice area is the largest. [Conclusion] There is a certain proportional relationship between the structural quantities and different ice areas, which can provide a reference for the estimation of the quantities of DC transmission lines in the future. |
