以河南省内近年建成投运的87条220k V架空线路工程为研究对象,根据地质、地形和气象条件等差异划分典型区域,运用统计学原理及数据分析方法,分析工程本体费用(含价差)和其他费用水平,并从自然地理条件和设计相结合的角度分析造价差异,以期为今后河南省220k V输电线路工程建设提供参考。 In this paper, 87 220k V overhead lines constructed and put into operation in Henan Province are taken as research objects. According to the differences of geology, topography and meteorological conditions, typical areas are divided. Statistical principles and data analysis methods are used to analyze the cost of engineering main body (including spreads) And other cost levels, and analyzes the difference in cost from the perspective of the combination of natural and geographical conditions and design so as to provide a reference for the future construction of 220kv transmission line in Henan Province.
