基于改进的FAHP评价法对桥梁施工质量评价
|
摘要
基于传统的FAHP评价法对桥梁施工质量进行评价时,隶属度矩阵通常是由隶属度函数法来确定的;但是,目前并没有一种科学合理的方法确定隶属度函数,多是由专家在其经验的基础上确定,从而导致评价结果带有一定的主观性。为了使评价结果真实地反映实际情况,在FAHP评价法的基础上,提出"比例法"来代替隶属度函数法确定隶属度矩阵,并以实际工程为案例进行验证,评价结果表明:"比例法"是以实际检测结果为基础,构造的隶属度矩阵与桥梁施工质量的真实状况相符,消除了隶属度函数法给评价结果带来的主观性;同时对评价结果进行分析,指出桥梁施工过程中存在的缺陷及安全隐患,并给出一些可行性建议及措施,对桥梁施工及后期管养有一定的指导作用。
Based on the traditional FAHP method in bridge construction quality evaluation,the membership degree matrix is often decided by membership functions, however, there is not a scientific and reasonable method to determine the membership function,it is determined by experts on their experiences,which makes the evaluation result often being certain subjectivity. In order to make the result of evaluation reflect real situation and on the basic evaluation method of FAHP,this paper puts "ratio method"to replace the membership function determine the membership degree matrix,with the example of practical engineering,the evaluating result shows that "ratio method"is based on the actual test results,the membership degree matrix is consistent of the real quality of bridge construction stituation,it eliminates the membership function method to bring the subjectivity of evaluating result. At the same time,it analyzes the result and points that the defects exist in the process of bridge construction and potential safety hazard,giving some feasible suggestions and measures,which has certain guiding role in the bridge construction and the late custody.
