多约束条件下城市道路复杂纵断面设计及评价

纵断面是城市道路设计中至关重要的环节,文章系统分析了纵断面设计的关键因素,针对目前多约束条件下的复杂纵断面方案比选缺乏依据,直观定性评价难以选择的实际情况,通过研究评价指标与评价方法的对应关系,提出了基于DEA方法的纵断面方案定量评价方法。

Design and Evaluation for Urban Road Vertical Section under Multi-constraint Conditions

Design of vertical section is a very important element in urban road design, the key factors are analyzed systemati- cally in this paper. In accordance with lack of selection reference, the quantitative evaluation method for vertical section de- sign based on DEA is proposed through studding on the relations between indexes and methods, so the problems of subjective and onesideness during selecting are solved.
