桥梁选型评价研究

Evaluation on Bridge Selection

在我国桥梁大规模建设和快速发展的同时,城市与公路桥梁在桥型选择方面存在的问题也引起桥梁工程师们的广泛重视。在桥型评价与桥梁选型方面,国内目前缺乏较为系统性的研究。针对公路桥梁桥型评价及选择,提出评价内容与方法,建立了评价体系。结合层次分析方法与模糊数学的相关理论,建立了城市与公路桥梁选型评价模型。本文研究成果为桥梁桥型选择提供了实用依据,对桥梁选型评价有一定的工程意义。

The problems existing in the selection of bridge types in the urban and highway bridges have invited increasing attention from the bridge engineers with the rapid development of bridge construction in our country, meanwhile there is a shortage of systematic research on bridge evaluation and selection. Therefore, it is necessary to study the reasonable selection of the bridge.Based on the selection of bridge types, this paper systematically studies the content and the method of the evaluation of highway bridges, puts forward an evaluation system that is based on the analytic hierarchy process（AHP） and fuzzy mathematics theory and establishes an evaluation model for the selection of urban and highway bridges. The research findings will provide a practical basis for the selection of bridge types.
