摘　　要：水利水电工程的地下洞室,常由于施工空间受限,严重影响洞内施工机械调度和协同。本文通过建立工期最短、成本最小的双目标优化函数,剖析地下洞室机械数量、工序时间、工序逻辑等约束,构建基于多智能体的有限空间地下洞室施工仿真模型,模拟复杂施工流程和施工机械的排队服务过程,分析施工机械在运行过程中的并行操作与潜在冲突,针对施工机械数量的变量调整,对比不同机械配置下的施工进度与成本,验证施工机械调度优化方案。引江补汉输水隧洞实例分析表明:25 t自卸汽车为最优装载量;随着隧洞掘进深入,有限空间内自卸汽车最优清渣数量呈动态递阶减少趋势,而非有限空间内呈现动态递阶增加趋势;优化后与原方案相比工期提前149.3天,费用节约3502万元,为施工组织设计和现场管理提供了决策支持。Underground caverns in water conservancy and hydropower projects are often faced with significant constraints due to a limited construction space,which severely affects the scheduling and coordination of construction machinery.This paper develops a dual-objective optimization function for minimizing both construction duration and cost,and examines various constraints on the construction,such as the number of machines,process time,and process logic.We construct a multi-agent-based simulation model for construction in confined space.It simulates complex construction processes and the queuing service process of construction machinery,and makes analysis of the parallel operations and potential conflicts of construction machinery during operation.Then we give a suggestion on how to adjust the number of construction machines based on the variables.Comparison of the simulations against the field observations of construction and its cost under different machinery configurations is conducted to validate the optimized schemes for construction machinery scheduling.A case study of the Yangtze-to-Hanjiang Water Diversion Tunnel shows a capacity of 25 t is optimal for dump truck loading.As the tunnel excavation progresses,the optimal number of mucking dump trucks in a confined space takes a dynamic hierarchical decreasing trend,while the trend is increasing for the trucks in a non-confined space.Compared with the original plan,our optimized schemes save 149.3 days in construction duration and 35.02 million yuan in cost,thus providing a better decision for construction design and scheduling and on-site management.
