摘要:: 价值工程是一门工程技术理论,其基本思想是以最少的费用换取所需要的功能。境外铁路项目设计中普遍采用价值工程的方法进行方案比选,通过优化功能与成本的比值关系,从而确定最有价值的线路方案。本文对价值工程工作方法进行了描述,以某境外铁路项目为例进行了方案比选分析,结果表明:(1)价值工程是一种科学管理方法,是功能对成本的比值,提高价值要通过调整功能与成本的比例关系来实现;(2)运用价值工程进行方案比选,要合理确定功能系数,降低工程成本,提高价值系数;(3)该境外铁路提速改造方案价值最高,其次为新建标准轨方案,下阶段应重点进行研究。本文研究成果可为境外铁路设计提供借鉴。

Abstract:: Value engineering is an engineering technology theory, and its basic idea is to acquire the required functions with the minimum cost. In the design of overseas railway projects, the value engineering method is widely used for option comparison and selection, and the most favorable route option can be determined by optimizing the ratio of function to cost. In this paper, the working methods of value engineering are described, and an overseas railway project is taken as an example for comparison and analysis of options. The results show that: (1) As a scientific management method, value engineering is the ratio of function to cost, and the increase in value can be achieved by adjusting the ratio of function to cost. (2) When the value engineering method is used for option comparison and selection, it is necessary to reasonably determine the functional coefficient, reduce the engineering cost and improve the value coefficient.(3) For this overseas railway project, the speeding-up reconstruction option is the most favorable one, followed by the new standard-gauge railway option, and these two options shall be studied in the next stage. The research results of this paper can provide reference for the design of overseas railways.
