摘　　要：针对大坝混凝土跳仓浇筑作业任务、资源与时间的耦合关系及优化排序问题,研发基于跳仓浇筑排序的多缆机调度模型及方法。分解大坝跳仓浇筑作业任务,分析缆机工作状态的任务变迁过程,厘定吊装、浇筑、吊运时间序列,建立大坝混凝土跳仓浇筑的缆机调度模型,制订跳仓浇筑模式下大坝缆机调度最优方案。案例分析表明:大坝缆机调度模型能缩短施工工期、节约生产资源,使缆机平均每小时工作时间提升4.88%、整体工期提前8.86%,可为缆机调度方案的制订提供理论支撑。Aiming at the coupling relationship between task,resource and time and optimal sequencing of dam concrete jump pouring,this paper develops a multi-cable crane scheduling model and method based on jump pouring sequencing.It decomposes the dam skip pouring task,analyzes the task change process of the cable crane working state,determines the hoisting,pouring and hoisting time series,establishes the cable crane scheduling model for dam concrete skip pouring,and formulates the optimal dam cable crane scheduling scheme under the skip pouring mode.The case analysis shows that the dam cable crane dispatching model can shorten the construction period and save production resources,increase the average hourly working time of cable crane by 4.88%and advance the overall construction period by 8.86%,which can provide theoretical support for the formulation of cable crane dispatching scheme.
