摘　　要：为实现山区铁路“隧道-环境”复合系统的良好协调演化发展,从微观要素视角构建“隧道-环境”系统耦合要素体系,运用耦合协调度模型分析其协调水平,采用双层复杂网络模型甄别提升隧道工程绿色化水平的主控要素,并构建“隧道-环境”耦合协调非线性优化模型(Non-Linear Programming, NLP),运用模拟退火算法(Simulated Annealing, SA)以主控要素为调控变量对其演化形态进行调控优化.以某山区铁路隧道工程为例分析其与隧址区环境的耦合协调关系.研究结果表明:“隧道-环境”复合系统的耦合协调初始值为0.675 8,系统处于初级协调状态,其耦合调控主控要素为隧道断面尺寸、洞渣利用率、洞口植被恢复率、衬砌渗透系数、注浆圈渗透系数、风机功耗,当各要素优化比例分别为12.72%、38.40%、44.06%、71.25%、30.00%、23.56%时,耦合协调最优演化值为0.799 0,达到良好协调状态;所构建的模型能够有效探析“隧道-环境”的协调演化路径,可为优化隧道工程绿色设计、促进山区铁路“隧道-环境”绿色协调发展提供新思路.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 enhancing the greening level of tunnel engineering.Then,a Non-Linear Programming(NLP)model is established 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 mountain railway tunnel project as a case study.The research results show that the initial coupling coordination degree of the“tunnel-environment”composite system is 0.6758,indicating a primary coordination 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 optimization ratios of these elements are 12.72%,38.40%,44.06%,71.25%,30.00%,and 23.56%,respectively,the optimal evolution value of coupling coordination is 0.7990,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.
