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 presupposition 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, then, the method and process of choice for optimum scheme are set up, and a project example is given to verify their practicality and feasibility.
