基于模糊层次分析法的混凝土梁桥拆除方案研究

Study on Demolition Scheme of Concrete Beam Bridge Based on Analytic Hierarchy Process

为保证桥梁的通行能力及耐久性要求,对不符合相关规定的桥梁,在无法加固维修或拓宽的基础上,拆除重建将是其唯一选择。为了从科学理性的角度给出明确的拆除方案选择思路,建立了基于模糊层次分析法的混凝土梁桥拆除方案选择模型;运用模糊层次分析法,以工程实例进行分析,对各种拆除方案进行综合评价,从而选择最优的拆除方案。

In order to ensure the traffic capacity and durability requirements of bridge,it is only one choice to demolish and rebuild the bridges not conforming to the relative specifications on the basis of hard to reinforce,maintain or widen.In order to give the clear idea for the selection of demolition scheme from the perspective of scientific rationality,the selection model for demolition scheme of concrete beam bridge based on the analytic hierarchy process(AHP)is established.AHP is used to analyze the engineering cases.Each demolition scheme is comprehensively evaluated so as to select the best demolition scheme.
