堆石坝工程土石方调配道路运输系统仿真研究

Study on Simulation of Traffic and Transportation System in Earth-rock Allocation of Rockfill Dam

为提高堆石坝工程土石方调配效率,分析了堆石坝工程土石方调配道路运输过程的特点和影响因素,并将系统划分为四个基本模型,采用仿真技术对交通运输系统模型进行模拟分析,获得了道路运输的行车密度、排队情况、机械利用率、机械故障率等信息,通过实例计算验证了土石方平衡调配方案的合理性,克服了传统仿真系统的不足,真实反映了实际道路的运输过程。

In order to improve allocation efficiency of earth and stone in rockfill dam project, this paper analyzes the operation characteristics and influencing factors of the road transport system in the process of roekfill dam project earth- work allocation. And then the system is classified as four modules. The information resulted from simulating includes the intensity of traffic flow, the numbers of trucks waiting for passing or loading, the utilization ratio of load and fault ratio of load and so on. Finally it testifies the feasibility of earthwork allocation balance program by examples. The system over- comes the deficiencies of the traditional simulation system, and trllhr reflects the actual road transport process.
