摘　　要：研究目的:新线设计中,接轨方案的选择是决策阶段需要解决的重要问题之一。接轨方案的选择主要是解决接轨点的选择和接轨方向的选择。本文通过对模糊综合评判的研究,为接轨方案的论证、优选提供一种量化的方法,以便做出较理想的线路设计。研究方法:从接轨方案选择的模糊性出发,确定影响接轨方案选择的各种因素,运用模糊数学的原理和方法对各种因素从理论上给予模糊综合评判,得出各个方案的优劣性。研究结果:通过对新建铁路田东至德保线接轨方案的实例验算,提出了推荐接轨方案,证明了本模型的可行性和实用性。研究结论:模糊综合评判模型在接轨方案的比选中有较强的应用价值,可为设计者提供决策依据;在实际应用中,可从比选方案自身特点出发,对模型的参数进行改进、优化。Research purposes： In the new railway designing, choosing the rail joint scheme is one of the important problems at decision phase. Choosing the rail joint scheme is mainly to determine the choice of rail joint junction and orientation. Through researching the fuzzy synthetic evaluation, one quantitative method is put forward for demonstrating and choosing optimum scheme, for making the best railway designing. Research methods：This paper analyzes all kinds of factors which influence choosing rail joint schemes. From the view of fuzziness on choosing optimum scheme from those to be demonstrated, fuzzy synthetic evaluation in theory are carried out for each factor by means of principle and way on Fuzzy Math. Research results：Through the testing of the newly - built railway between Tiandong and Debao, the recommended scheme is put forward and the feasibility and practicability of the method is demonstrated. Research conclusions ：The fuzzy synthetic evaluation method is valuable for choosing the rail joint scheme, and can provide decision- making to designers. In practical application, the method could be optimized according to the different schemes.
