摘　　要：长距离输水隧洞检修期排水时,壁面附着的淡水壳菜会死亡腐烂并释放出大量有害气体,严重威胁检修安全。现有地下工程通风安全研究侧重于考虑通风效果的通风方案比选,难以获取兼顾通风效果和通风成本的全局最优方案,且缺乏考虑淡水壳菜腐烂有害气体的影响。此外,基于帕累托最优准则(PO)的多目标优化方法在输出非支配解集后,需要结合多准则决策方法进行二次选择方可得到最优解,优化效率较低。针对上述问题,提出考虑淡水壳菜腐烂影响的长距离输水隧洞检修通风方案模糊逻辑多目标优化方法。首先,结合模糊隶属度函数将多个优化目标转换到相同的连续域空间,并综合处理成统一的优化指标,构建基于模糊逻辑(FL)的多目标优化数学模型,以进行兼顾通风效果与通风成本的全局寻优;然后,提出基于混沌映射和最优邻域扰动策略改进的沙漠猫群优化(ISCSO)算法求解多目标优化数学模型,避免非支配解集的二次选择,提高优化效率。性能测试和案例研究表明,本文提出的ISCSO-FL多目标优化方法在解的质量、解的鲁棒性以及计算复杂度等方面具有优越性。本文方法得到的最优方案能够满足通风安全需求,通风成本相比初始方案降低21.9%,且优化效率相比基于PO准则的多目标优化方法提高68.1%。本研究可为地下工程通风方案的设计与优化提供新思路。The mussels attached to the long-distance water tunnel wall may die and decay due to the maintenance drainage and release a lot of harmful gases,which seriously threatens the maintenance safety.However,the existing researches on ventilation safety of underground engineering focus on the comparison and selection of ventilation schemes considering ventilation effect,which is difficult to obtain the global optimal scheme that balance ventilation effect and ventilation cost,and the influence of harmful gases from mussel decay is ignored.Moreover,the multi-objective optimization method based on Pareto optimality(PO)requires the secondary selection of the non-dominated solution set combined with multi-criteria decision method to obtain the optimal solution,which leads to the reduction of optimization efficiency.To solve these problems,a fuzzy logic multi-objective optimization method for maintenance ventilation scheme of long-distance water tunnel considering the effect of mussel decay is proposed.First,the fuzzy membership functions are combined to transform multiple optimization objectives into the same continuous domain space,the unified optimization index is synthesized,and a multi-objective optimization mathematical model based on Fuzzy logic(FL)is constructed for global optimization.Then the improved sand cat swarm optimization(ISCSO),based on chaotic mapping and optimal neighborhood disturbance strategy,is used to solve the mathematical model to avoid the secondary selection and improve the optimization efficiency.Performance test and case study show that the proposed ISCSO-FL method has advantages in solution quality,solution robustness and computational complexity.The optimal scheme obtained by ISCSO-FL method can meet the ventilation safety requirements,the ventilation cost is reduced by 21.9%compared with the initial scheme,and the optimization efficiency is increased by 68.1%compared with the multi-objective optimization method based on PO.This study can provide a new idea for the ventilation scheme design
