山区铁路隧道工程与区域环境耦合协调状态优化
Optimization of coupling coordination state between tunnel engineering and regional environment in mountain railway
摘要
Abstract
To achieve the optimal coordinated evolution and development of the"tunnel-environment"composite system in mountain railways,a coupling element system is constructed from the perspective of micro-elements.The coordination level is analyzed using the coupling coordination degree model.Next,a double-layer complex network model is used to identify the main control elements for enhanc-ing the greening level of tunnel engineering.Then,a Non-Linear Programming(NLP)model is estab-lished to quantify the coupling coordination connection of"tunnel-environment",and the Simulated Annealing(SA)algorithm is further applied to regulate and optimize its evolution process,using the main control elements as the control variables.Finally,an analysis is conducted using a specific moun-tain railway tunnel project as a case study.The research results show that the initial coupling coordina-tion degree of the"tunnel-environment"composite system is 0.675 8,indicating a primary coordina-tion state.And the main control elements for coupling regulation are the tunnel section size,tunnel slag utilization rate,vegetation restoration rate at the tunnel entrance,permeability coefficient of the lining,permeability coefficient of the grouting circle,and fan power consumption.When the optimiza-tion ratios of these elements are 12.72%,38.40%,44.06%,71.25%,30.00%,and 23.56%,respec-tively,the optimal evolution value of coupling coordination is 0.799 0,achieving a well-coordinated state.The proposed model effectively explores the coordinated evolution path of the"tunnel-environment"system and provides new insights for optimizing green tunnel design and promoting the green and coordinated development of"tunnel-environment"in mountain railways.关键词
