摘要
我国输电杆塔基础型式多样,这主要与我国地域辽阔,岩土类别多、分布广,各地区地形地貌和地质条件差异大等区域性特点决定的。近年来,我国在架空输电线路基础方面的研究取得了较大的进步,基于输电杆塔基础的受力特点、工程造价及环境保护等要求,研发了多种新型输电杆塔基础形式。集合国内外学者的研究结果,主要针对不同输电杆塔基础型式进行了分类阐述,给出了各种基础型式在理论、试验、数值模拟等领域的研究现状与尚存不足,同时对其适用性进行了评价,并对后继研究前景进行了展望。
There are lots of types of transmission tower foundation in China,mainly because of vast territory,more kinds of soil and rock,and complex geological conditions. In decades,great achievement was already got in research about overhead transmission foundation.Based on the demand of loading characteristic,building cost of projects and environmental protection,many kinds of foundation was already researched.This paper gathered together the findings of scholars,mainly aim at the different type of transmission tower foundation were classified elaborate,given the lack of research status of more kinds of foundations in the areas of theory,experiment and numerical simulation,meanwhile evaluated the applicability,and subsequent research prospected.
