摘要
针对高海拔、特重冰、峻岭地区输电线路导地线荷载大、地形陡峭、铁塔根开大、铁塔级差有限、基础工程量大、常规施工方法效率低等特殊问题,结合工程设计经验,从全过程经济性、可靠性、可行性以及环保性综合考虑,提出了送电结构专业的创新措施,包括3种钢架延长腿、三类新型铁塔、两种新型基础方案。
Aimed at steep mountains with high altitude and heavy icing,the transmission line has some special problems,such as heavy load of earth wire,steep terrain,large size of tower,lack of tower legs,large amount of foundation project quantity and low efficiency of conventional construction methods.Combined with the rich experiences in engineering design,and from the comprehensive consideration of economy,reliability,feasibility and environmental protection in the full cycle,the structure innovation measures of transmission line are put forward,including three kinds of steel to extend the leg,three kinds of new tower type and two kinds of new foundation type.
