摘要
Abstract
According to《Technical Regulation of design for tower and pole structure of overhead transmission line》(DL/T5154-2002),the strength analysis of the square tower foot plate under compression should be calculated with the uniform reaction force(Putting aside the correctness of this view), in no longer checking the concrete local compression under the tower bottom plate;steel tube tower foot flange plate is an annular area of the base plate and the thickness of the plate is often less than the square tower foot plate, which concrete local compression of the calculation were not listed in the present Code and Technical regulations;for"1000kV Huainan-Shanghai (Anhui Power East) transmission line ", the project was made up of double-loop steel tube tower, the foot flange bolts using a small diameter of specifications and more number, with the calculation method proposed in this paper, which can meet the local compression of the concrete column under the tower feet.关键词
