摘要
实践表明,铁路建设中的35kV及以上电力迁改项目,普遍存在:前期调查深度不够、实施中设计方案多次修改、投资超概算现象普遍、工期拖延等问题。鉴于目前现有的铁路工程造价标准体系缺少迁改工程相应的定额体系,也没有明确的迁改工程费用计算公式。本文研究建立在对某沿海发达省份“十三五”期间具有代表性的铁路建设项目各阶段35kV及以上电力迁改工程费用实际发生情况统计分析的基础上,采用特征价格法,建立了一套铁路建设项目35kV及以上电力迁改工程费用预测模型,填补国内空白,解决铁路建设项目35kV及以上电力迁改工程投资控制中遇到的诸多难题,为铁路建设项目迁改工程投资控制的建设者提供参考依据。
Practice has shown that the 35kV and above power transformation projects in railway construction generally exist problems such as insufficient depth of investigation in the early stage,repeated modification of the design scheme in the implementation,widespread overestimation of investment,and delay of construction period.In view of the current standard system of railway engineering cost,there is no corresponding quota system for the relocation project,and there is no clear calculation formula for the relocation project cost.Based on the statistical analysis of the actual cost of 35kV and above power transfer and transformation projects in each stage of representative railway construction projects in a province during the 13th Five-Year Plan period,this study adopted the characteristic price method to establish a set of cost prediction model for 35kV and above power transfer and transformation projects of railway construction projects to fill the domestic gap.It solves many problems encountered in the investment control of 35kV and above power transfer engineering of railway construction projects,and provides a reference for the builders of the investment control of railway construction projects.
