基于灰色关联分析的软土地基公路建设路桥结构选型决策研究

通过对软土地基公路建设的分析,确定路桥结构选型决策的主要影响因素包括工程造价、行车质量、土地占用以及公路对周边地区环境和发展的影响等四个方面。运用灰色关联分析理论,提出了一种软土地基公路建设路桥结构选型决策的方法,并以广州绕城高速公路西二环段为例进行选型程序的实施与分析研究,验证了该方法的可行性,为软土地基新建公路的结构决策提供参考和借鉴。

Research on the Highway Structures Selection Decision for Soft Ground Highway Construction Based on Grey Relational Analysis

Based on analysis on construction of highway through soft soil area, the main influencing factors of the highway structures selection decision has been determined to include such four aspects as including project cost, driving quality, land use and impact of the highway on the environment and development of the surrounding area. From grey relational analysis theory, a selection decision method for highway structures on soft soil area has been pointed out, and taking Guangzhou Second Western Ring Expressway Project as an example, the implementation and analysis for selection procedures have been carried out, which has verified the feasibility of the method and can provide reference for decision-making for structure of new highway through soft soil area.
