摘要
为提取科学有效的电力技术经济指标,进行电力工程造价的全过程管理和造价分析,基于以往建设工程积累的历史数据,以架空输电线路工程安装费用作为研究对象,提取单位塔材质量造价作为技术经济指标,通过统计分析及对比,论证了塔材质量与安装费用具有强相关性,且各工程的指标数据呈正态分布,便于造价数据的统计分析和对比研究。
In order to extract scientific and effective technical and economic indicators of power and carry out the whole process management and cost analysis of power engineering cost, based on the historical data accumulated in previous construction projects, the overhead transmission line project installation cost is taken as the research object, and the unit tower material quality cost is extracted as the technical and economic indicator. Through statistical analysis and comparative verification, it is demonstrated that the tower material quality has strong correlation with the installation cost, and the index data of each project are distributed normally, which is convenient for statistical analysis and comparative study of cost data.
