【摘要】：混凝土面板堆石坝以其安全性、经济性和良好的适应性在我国西南地区水电开发中得到了广泛的应用。堆石坝建设工程量大，工期紧，施工强度大，场内交通运输系统（包括土石方开挖运输系统，，土石方上坝运输系统，混凝土浇筑运输系统以及其他运输系统）承担着整个工程的各种运输任务，其合理安排和规划对整个工程的施工进度、投资和安全运行都具有重要的影响。本文针对面板堆石坝场内交通运输系统的特点，基于实时监控系统的监控数据，获取高精度的施工参数及边界条件，对梨园面板堆石坝坝料的土石方调配进行了研究，对大坝填筑期间的施工场内交通情况进行了仿真计算，并将仿真成果与监控成果做了对比分析，提出了改进意见。主要研究成果如下： （1）针对面板堆石坝场内交通运输过程的特点，对面板堆石坝场内交通仿真建模理论进行了研究。通过对其基本特征和运输过程进行描述、分析和假定，对其影响因素进行分析，最终描述出整个交通仿真流程，并详细研究了整个面板堆石坝场内交通仿真过程。 （2）针对土石方调配成果和实时监控信息对面板堆石坝场内交通仿真的影响，对基于土石方调配和实时监控信息的面板堆石坝场内交通仿真进行了研究。通过分别详细分析二者对交通仿真参数和边界条件的影响，将相关仿真数据进行分析处理，建立了梨园面板堆石坝场内交通仿真模型。 （3）基于梨园水电工程土石方调配成果和实时监控信息的数据分析成果，对梨园水电工程大坝填筑期间的场内交通运输情况进行了仿真分析，将仿真结果与上坝运输实时监控结果进行对比研究，并据此对面板堆石坝施工场内交通仿真提出了相应的改进意见，为提高面板堆石坝施工场内交通仿真的精度和可信度提供了必要的支持，具有良好的应用价值。
[Abstract]:Concrete faced rockfill dam (CFRD) has been widely used in hydropower development in southwest China because of its safety, economy and good adaptability. The construction quantity of rockfill dam is large, the construction period is tight, the construction intensity is large, and the transportation system in the field (including earthwork excavation and transportation system, earth-rock work-up dam transportation system), Concrete pouring transportation system and other transportation systems undertake all kinds of transportation tasks of the whole project, and their reasonable arrangement and planning have an important influence on the construction schedule, investment and safe operation of the whole project. In this paper, according to the characteristics of the transportation system in the concrete face rockfill dam yard, based on the monitoring data of the real-time monitoring system, the high-precision construction parameters and boundary conditions are obtained, and the earth-rock allocation of the dam material in Liyuan concrete face rockfill dam is studied. The traffic situation in the construction yard during the filling period of the dam is simulated and calculated. The simulation results are compared with the monitoring results, and the suggestions for improvement are put forward. The main research results are as follows: (1) according to the characteristics of the transportation process in the concrete face rockfill dam site, the traffic simulation modeling theory in the concrete face rockfill dam site is studied. The basic characteristics and transportation process are described, analyzed and assumed, and the influencing factors are analyzed. Finally, the whole traffic simulation process is described, and the traffic simulation process in the concrete face rockfill dam yard is studied in detail. (2) in view of the influence of the results of earthwork allocation and real-time monitoring information on the traffic simulation in the concrete face rockfill dam site, the traffic simulation of the face-faced rockfill dam site based on the earth-rock allocation and real-time monitoring information is studied. By analyzing the influence of them on traffic simulation parameters and boundary conditions, the traffic simulation model of Liyuan face rockfill dam yard is established by analyzing and processing the relevant simulation data.
