铁路线路智能优化理论与方法研究综述
A Research Review on Theories and Methods for Intelligent Optimization of Railway Alignment
摘要
Abstract
Railway route selection design is a fundamental prerequisite for ensuring the safety,economy,comfort,and environmental sustainability of railway alignment.A thorough investigation into intelligent alignment optimization,the core link of the design,is therefore of great significance to improve the quality and search efficiency of alignment schemes.The essence of intelligent alignment optimization lies in constructing multi-objective optimization models under multi-dimensional and multi-factor environments,and developing intelligent search algorithms to obtain optimized alignment solutions.Accordingly,the domestic and international research on intelligent railway alignment optimization are systematically classified and reviewed from 3 aspects:multi-dimensional environmental modeling,alignment optimization modeling,and search algorithms.The results show that,under multi-dimensional enviroment,research have evolved from early digital terrain model and digital geological model to comprehensive geographic information models that integrate multi-dimensional environmental factors.In terms of model optimization,the focus has shifted from independent optimization of horizontal and vertical alignments to integrated horizontal-vertical optimization,and evaluation indicators have gradually expanded from engineering economics to include multiple objectives such as safety,sustainability,and low-carbon performance.The solution algorithm has evolved from early analytical approaches to heuristic algorithms,and more recent studies have emphasized deep integration with fields of knowledge-based reasoning and artificial intelligence,leading to a higher degree of intelligence.In the future,the intelligent optimization of alignment will be more proactive and comprehensive in geographic information services,more diversified and integrated in evaluation objectives,and more intelligent and efficient in search methods.关键词
