摘要
架空送电线路由于长期经受荷载以及恶劣环境等作用,铁塔构件会出现弯曲,腐蚀等现象,严重影响送电线路安全稳定运行。依据现有研究成果,首先提出基于层次分析法的铁塔结构安全状态评价方法;其次利用专家调查方法实现评价项目权重开放式计算;最后提出利用变权综合法计算铁塔结构安全状态评分值。这些研究成果的提出,基本上建立了一套比较完整的线路铁塔结构安全状态评价体系。
The towers of overhead transmission line have experienced loads and abominable surroundings,the members have been bending and rusting,which affect the function of overhead transmission line.At first,according to the existing research results,safe condition estimation method based on analytic hierarchy process(AHP) had been advanced;secondly,the weight of estimated items had been calculated by expertise;at last,the safe condition estimation score of the tower by variational weight compositive method had been advanced.A system of safe condition estimation for the tower of overhead transmission line had been set up by these scientific achievements.
