Theory and practice of construction simulation for high rockfill dam

Construction simulation for high rockfill dam (CSHRD) is the technology that takes advantage of computer simulation to observe and analyze a complex construction process, which is useful for construction design and management. In this paper, the domestic and oversea research status of CSHRD is reviewed firstly, along with introduction of their present achievements and deficiencies, and the CSHRD theory is also described. Then, considering the influence of many stochastic factors, integrated simulation for high rockfill dam construction (HRDC) is presented with technologies of cycle operation network (CYCLONE) and computer simulation. It rationally combines two subsystems in HRDC, namely haulage and placement of rockfill subsystem, which reflects the actual construction objectively. Important parameters, such as the haulage intensity and traffic density, are obtained, and the process of CSHRD is represented intuitively in dynamic visualization. All of these help engineers to make rapid decisions in HRDC scientifically.
