摘要研究目的:铁路主要技术标准是铁路建筑物、设备类型、能力和规模的基本标准，所以铁路主要技术标准选择是一个多目标决策问题。本文针对铁路主要技术标准选择这一多目标决策难题，依托几内亚西芒杜矿山铁路主要技术标准选择的生产实践，通过多目标决策模型来实施辅助决策，以求探索出一条科学合理地解决铁路主要技术标准选择这一多目标决策难题的技术可行性思路。

研究结论:(1)铁路主要技术标准是制约铁路线路方案选择和铁路设计的基本约束条件;(2)将铁路主要技术标准选择定义为一个多目标决策问题具有科学性、合理性:(3)基于线型加权和法多目标决策模型的铁路主要技术标准选择是一条科学合理解决铁路主要技术标准这一多目标决策难题的技术可行性思路:(4)基于多目标决策模型的铁路主要技术标准选择的技术路线可应用于国内外高速铁路、普速铁路和货运铁路等领域。

Abstract：Research purposes: The main technical standards for railway are the basic standards for the railway 's buildings and equipment type，capacity and scale. So the selection of main technical standard for railway is related to the mufti-objective decision-making. Aiming at the difficulty in multiple objective decision-making for the selection of main technical standards for railway and based on the actual selection of main technical standards for the Guinea Simandou Railway，the auxiliary decision-making was implemented by using the mufti-objective decision-making model in order to explore a technically feasible ideas on overcoming the difficulty in the selection of main technical standards for railway based on the mufti-objective decision-making.

Research conclusions:(1)The main technical standards for railway are the basic constraint conditions for the railway alignment and design. ( 2 ) It is scientific and reasonable to define the selection of main technical standards for railway as an issue of multiple-objective decision-making.(3)Based on the mufti-objective decision making model with the linear weighted sum method for selection of main technical standards for railway is a technically feasible ideas on overcoming the difficulty in the selection of main technical standards for railway based on the mufti-objective decision-making. (4)The technical route of the selection of major technical standard for railway based on the mufti- objective decision-making model is available for the high-speed railway，ordinary speed railway and freight railway.

Key words： multi-objective decision-making main technical standard axle load traction weight ruling grade: linear weighted sum method
