摘　　要：榆横—潍坊特高压交流输变电工程途经山东淄博地区,多为丘陵、山地,部分塔位地形恶劣,坡度达50°以上,采用常规铁塔方案存在一定困难。针对13R159号和13L164号两基位于"刀背山"的单回路铁塔的实际情况,介绍塔位地形地貌和地质条件,对比常规转角塔JC30151A方案和特殊分体塔FT3015A两种方案的根开、塔重、塔腿高差、基础规格和基础工程量等方面,确定分体塔FT3015A的设计方案,并从铁塔设计、塔位布置和基础配置几个方面详细介绍分体塔的设计过程,得出一些有益的结论,为今后山区特高压工程提供借鉴。Yuheng-Weifang ultra-high voltage （UHV） transmission line project crosses through Zibo, where the physiognomy is mainly hill and mountain. The terrain condition of some towers is such unfavorable with slope up to 50 degree that normal tower is not adaptable. Aiming at actual conditions of No. 13R159 and NO. 13L164 foundations, their physiognomy and topography are introduced. The normal planning of single circuit tower JC30151A and the particular planning of split tower FT3015A are compared with respect to base width, tower weight, altitude difference, foundation planning and foundation quantities, and the planning of split tower FT3015A is adopted. The design process of split tower is presented with respect to tower design, tower arrangement and foundation allocation. Some useful conclusions are obtained as references for UHV projects.
