Research on Quarry Excavation Modeling of Concrete Face Rockfill Dams Based on Earthwork Balance

The subject of concrete face rockfill dams(CFRD) are rockfills.During the construction of CFRD,the analysis and management of excavation process are crucial,and it is impossible to smooth construction if there is no enough rockfill sources,meanwhile,it is hard to achieve the integrated optimization of overall project.In order to achieve such goals as rapid construction,reasonable strength,saving economic of the overall project,based on the study of simulation modeling,combing the balanced allocation process of earth-rock work,this paper establishes the joint model of "quarry excavation process and balancing allocation of earth-rock work" and achieved the real-time dynamic simulation and management control of construction process of quarry excavation,it can provide convenient and fast management platform and reliable data to support engineering design and decision-making.
