摘　　要：混凝土运输车数量选型的配置对工程项目成本控制、质量保证具有重要的意义,然而,现阶段运输车数量的配置多为经验性配置.按混凝土连续灌注及最优经济性的原则,建立了运输车优化配置的数学模型,并通过算例验证了其正确性及可行性.分析表明:随混凝土需求量的增加运输车配置数量先增大后稳定(即车辆配置数量达到饱和状态);增大运输车容量后工点灌注完成时长会缩短,然而对饱和状态的配置数量没有影响.The configuration of the number of concrete trucks is of great significance to project cost control and quality assurance.However,the current configuration of the number of trucks is mostly empirical.In this paper,according to the principle of continuous concrete pouring and optimal economy,the mathematical model of optimal allocation of transport vehicles is established,and its correctness and feasibility are verified by calculation examples.The analysis shows that the number of transport vehicles increases first and then stabilizes with the increase of concrete demand(that is,the number of vehicles reaches saturation state).In addition,with the increase of transport vehicle capacity,the completion time of construction site will be shortened,but it has no effect on the number of configurations in the saturated state.
