山区铁路桥梁与区域环境耦合协调测度及优化调控
Measuring and Optimizing Coupling Coordination Between Railway Bridges in Mountainous Regions and the Regional Environment
摘要
Abstract
The terrain along the mountain railway is intricate,with a high proportion of bridges.To systematically evaluate and enhance the har-mony between mountain railway bridges and the regional environment,fostering their high-quality coordinated development,we propose a coupled coordination optimization and control model for mountain railway bridges and the regional environment.This model is based on an ana-lysis of the interplay between mountain railway bridges and the regional environment.We construct green design elements and a characteristic in-dex system for mountain railway bridges from a design perspective and utilize the CRITIC method to identify key elements of green design.In-corporating the cumulative effect of time,we analyze the sustainability of mountain railway bridges and the environmental carrying capacity,and develop a coupling coordination model for the mountain railway"bridge-environment"system,measuring the degree of coupling coordination between mountain railway bridges and the regional environment.By maximizing the coupling coordination index as the objective function,we es-tablish an optimal regulation model that reflects the dynamic feedback mechanism of the"bridge-environment"system.This model is solved us-ing the particle swarm optimization algorithm,and a control scheme is proposed to guide the coordinated development of mountain railway bridges and the regional environment towards high quality.Our optimization results indicate that,while ensuring"bridge sustainability≤environ-mental carrying level"and minimizing deviation,the optimization ratio of key green design elements ranges from 2%to 40%,resulting in a max-imum coupling coordination index of 622.4 for the"bridge-environment"system.This study enhances the coordinated development of bridges and the regional environment,offering fresh perspectives for assessing the coupled coordination status of mountain railway bridges and the re-gional environment,as well as for green bridge design.关键词
