摘　　要：针对TBM法施工排水廊道工程中的不确定因素,基于关键路径法建立施工工期、作业成本、工程质量3个目标函数,以不同工序下的施工组织方式为决策变量,建立综合考虑三者风险的综合优化模型。为求解该模型,提出一种通过更新放电体能量并改变放电体迭代方式的新型闪电搜索算法,并由3组测试函数仿真验证新算法的有效性。通过浙江缙云抽水蓄能电站排水廊道开挖工程对模型进行实例验证,采用改进闪电搜索算法来求解施工组织综合优化模型,得到多组分布较为均匀的三维Pareto最优解,优化结果表明,多目标施工组织管理综合优化模型具有合理性,改进闪电搜索算法具有一定的有效性,可为决策者提供准确直观的施工组织管理依据。To address the uncertainties in construction of drainage gallery by TBM method,the 3 objective functions including construction duration,work cost and work quality have been established by using the critical path method,and the integrated optimization model that takes into account the risks in the 3 objective functions has been created by using the construction organization methods in different construction processes as the decision-making variables.To solve this model,a new lightning search algorithm has been invented by updating the energy of electric discharge body and changing the iteration method of electric discharge body,and the effectiveness of the new algorithm has been verified through simulation of the 3 sets of test functions.The example verification of the model has been con⁃ducted by using the excavation of the drainage gallery of Zhejiang Jinyun Pumped Storage Power Station as the exam⁃ple.The integrated optimization model has been solved by using the improved lightning search algorithm,to generate several sets of 3D Pareto optimal solutions that are evenly distributed.The results of optimization prove the rationali⁃ty of the integrated optimization model for multi-objective construction organization and management and the effec⁃tiveness of the improved lightning search algorithm,and thus afford the basis for the decision makers to conduct pre⁃cise and intuitive construction organization and management.
