Abstract 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.
