Analysis on the appraising & scheme selection of deep soft roadbed reinforcement : case in meihe expressway project

Abstract

高速公路深层软基处理方案的选择涉及诸多因素,由于缺乏有效的技术-经济评估方法,以往对的方案选择往往过于注重技术可行性。这是不全面的。本文基于层次分析技术(AHP),建立了一个新的评估模型,模型的参数则通过专家的群决策知识确定,通过将多因素量化集成,得出了综合指标,用于不同方案的评价和选择,梅河高速公路建设的实践表明,这种方法十分有效并且简捷。 The appraising & scheme selection of deep soft roadbed reinforcement involved in many factors,conventional methods of appraising and scheme selection are mainly weighed on technical feasibility,which cannot meet the requirement in practice.In this paper the main objective is to set up a new model based on Analytic Hierarchy Process(AHP) approach and expert’s group decision supporting technique.Then a concrete case study is carried out,which shows that this new model is very effective and convenient to apply. 还原
