[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. (3) based on the data analysis results of earth-rock allocation and real-time monitoring information of Liyuan Hydropower Project, the traffic and transportation situation in the field during the filling period of Liyuan Hydropower Project is simulated and analyzed. The simulation results are compared with the real-time monitoring results of the upper dam transportation, and the corresponding suggestions for improving the traffic simulation in the construction site of the concrete face rockfill dam are put forward according to the simulation results. In order to improve the accuracy and credibility of traffic simulation in concrete face rockfill dam construction site, it provides necessary support and has good application value.
