Research On Comprehensive Utilization Theory And Method Of Urban Rail Transport Underground Space In Mountain Area

Nowadays, the demand of land resource in Chinese cities is especially highbecause the urbanization process is at its peak. However, the limited land recoursecontains this process. The using of underground recourse, on the other hand, can helprelieve this problem and low down the environment effect, which is one of the mainurbanization developments in China. The underground rail transport utilization leadsthe underground recourse exploitation not only for its transport advantage, but also forits effects on distribution of urban function that it improves the urban layout. As oneof the important infrastructure, underground rail transport plays a decisive role both inthis world.This research put its attention on the importance of underground rail transport forthe urbanization firstly, and pointed out the difficulties and problems of how toexplore it by collecting and analyzing the plan, geology construction condition andlaw based upon the realistic construction of Chongqing rail transport.The following research laid its emphasis on the technology and economy of howto exploit the underground rail transport resource. The former put the current technicalprinciple, regulation and measures ahead, and then studied the interaction between theunderground rail transport and structures around. It especially promoted thedevelopment range of the horizontal direction and the vertical direction by analyzingproblem, extracting the parameters, modeling by ANSYS and data analysis. The laterresearched its exploitation superiority, characters and mode, and emphasized thenecessity of investment integration between government and private capital. There aresome unique points in both of them.The research established the comprehensive utilization of evaluation system forthe underground rail transport and proposed the evaluation index. In the lastevaluation process, the experts hardly gave out the same opinion, which made thecalculation process of score complex. By the modified group decision method, thisdisadvantage can be solved.
