| Hydroelectric projects tend to have a narrow construction site,the construction of high strength,resulting that the layout of construction site roads is difficult.Using computer simulation method to analysis the traffic condition of construction site,may improve the design quality of construction site transportation system and the disposition of earthwork construction equipment,which is of great significance to ensure the construction schedule,reduce the project cost.Based on the characteristics of hydroelectric project transportation and system simulation theory,this paper studies the traffic simulation model of large-scale hydroelectric engineering projects construction based on agent theory,and discuss the structure attribute and simulation mechanism of the traffic simulation agent.The main research contents and results are as follows:(1)According to the characteristics of the transportation system,this paper studies the transportation system modeling theory.Based on that,this paper analyzes the components of transportation system in the hydraulic project construction site,analyzes and describes its basic characteristics and transportation process,analyzes its influencing factors,By which this paper determines the simulation model of the construction hydroelectric engineering projects.Finally,the simulation process of the transportation system in the whole construction site is described.(2)Based on the research of Agent theory,this paper analyzes the structure and basic characteristics of the Agent,and analyzes the model of the agent communication.Based on the structure of Agent and the characteristics of system,the paper analyzes the characteristics of traffic agent,loader agent,unloading platform agent,intersection and traffic lights agent,Based on the agents the architecture of Agent-based traffic simulation system is established,and the structure and properties of each Agent are analyzed scientifically.At the same time,this paper proposes the original vehicle transportation model of transportation system,and further considers the influence factors,such as the road alignment and the driver characteristics,which makes the simulation results more believable.(3)The C# language is used as the developing tool and the Agent technology framework is developed to design the Agent-based traffic simulation system for the hydroelectric engineering projects.Through verification it is proved that the system has good flexibility and effectiveness.(4)Through the simulation and calculation of transportation in the construction site of a large-scale hydroelectric engineering project,which demonstrate the demonstration process of the simulation system,and compare the simulation results with the relative specifications,which proves that the simulation system can provide technical support for the construction design and the management of the project. |
