摘要
随着经济快速发展,珠江三角洲地区高速公路路桥比选需要考虑多种因素的影响,可采用基于灰色关联理论的最大关联度法进行路桥比选。考虑相邻路段方案、比选范围工程造价组成、行车质量等,将路桥比选分为三类;基于已有研究成果、工程实践经验、专家调查等,确定了最大关联度法的比选因子、代表性指标及其权重,并提出路基工程造价考虑维修费用的方法,最后利用实际工程验证了最大关联度法对珠三角高速公路路桥比选的适用性。
With the rapid development of economy of the Pearl River Delta of China, many kinds offactors should be taken into account for comparison of embankment and bridge and maximum correlation method based on grey correlation analysis theory may be applied. Comparison of embankment and bridge can be classified 3 kinds in view of the differences of schemes of adjacent section, components of compari- son range, driving quality. Comparison factors, respective indexes and weights for maximum correlation method are gotten and method to take maintenance cost into construction cost is proposed based on current research production, engineering experience and expert investigation. Finally the serviceability of maxi mum correlation method for comparison of embankment and bridge of expressway in the Pearl River Delta of China is proven by a project.
