Based on the basic principles of Standard for urban rail transit network planning, a three-stage line laying mode by means of the experience in laying urban rail transit lines is put forward, that namely key node/section laying mode, adaptability evaluation of laying mode and economic comparison. Based on the basic principle of fuzzy analytic hierarchy process, combining with the characteristics of Jinan cultural and geographical environment,the adaptability evaluation laying method and algorithm is put forward and three-stage fuzzy hierarchical line laying mode is formed. The study on the laying mode of Jinan rail transit line 1 shows that: through the analysis of key nodes/sections, it can be determined that the four stations between Fangte station and shuitun station of Beijing-Shanghai railway are underground stations, and the underground laying (shield construction method) is adopted in the interval. According to the adaptability evaluation of the laying method based on fuzzy hierarchical analysis, the membership of underground laying and elevated laying between Shuitun station of Beijing-Shanghai rail ray and Gongyanyuan station is 0.499 and 0.501 respectively, and there is no significant difference between the two laying methods. According to the economic comparison, the overhead laying can save 42.4% compared with the static discounted present value of underground laying between the Shuitun station of the Beijing-Shanghai railway and Gongyanyuan station, so it is suggested to choose the overhead laying, which is consistent with the actual result.
