桥梁加固方案的层次分析优选法

桥梁加固技术是目前桥梁工程的新热点，选择科学的加固方案是保证工程效果和质量的重要前提。为了合理地确定桥梁加固的最佳方案，总结出技术可行、效果可靠、经济合理和施工方便等影响桥梁加固方案评价的因素，利用层次分析原理中多规则决策问题的基本思路，以桥梁加固最佳方案为基本目标，建立2级综合评价指标体系，应用层次分析方法分解评判指标体系，得出判断矩阵和评价矩阵，给出层次分析评价过程和加固方案优选的决策方法，并结合工程实例说明层次分析法在桥梁加固方案选择中的实用性和可行性。

Choice of Optimum Scheme for Bridge Strengthening by Using Analytic Hierarchy Process

Bridge strengthening technology is a new hot spot of bridge engineering now,and choice for a scientific strengthening scheme is an important requisite to ensure the effectiveness and quality of a project.In order to decide the optimum strengthening scheme reasonably,in this paper,the factors such as the technological feasibility,the effect reliability,the economic reasonability and the work's convenience which influence the appraisal for bridge strengthening schemes are summarized.Based on the basic objective for the optimum scheme,two levels comprehensive appraisal index system of strengthening scheme are established,and the dividing levels are analyzed by using the principles of Analytic Hierarchy Process(AHP).And the judgment matrix and the appraisal matrix are listed,the method and process of choice for optimum scheme are set up,and a project example is given to verify their practicality and feasibility.
