Study On Construction Dynamic Visual Simulation And Optimization For Jinanqiao Roller-compacted Dam

The construction of roller-compacted dam (RCD) is a rather complex system,which is affected by many factors, and is also restricted by flooding, constructiondiversion, generation time etc. So it's meaningful to the construction organizationdesign by providing information like typical construction visage, time limit for theproject, pouring intension and efficiency of the equipments, so that the comparison ofschemes can be carried out quickly and exactly. Since the construction for JinanqiaoRCD is complicated, with high intension, a new methodology of constructionsimulation for Jinanqiao RCD is presented, which combines object-orientedsimulation modeling, software engineering, system simulation and 3D visualization.The main contents and achievements of the paper are summarily listed as following:Firstly, based on the analysis to the construction system, a modeling frameworkfor RCD construction is built by using the technology of object-oriented simulation.The methodology of simulation modeling course for Jinanqiao RCD is expatiated.Secondly, construction simulation for Jinanqiao RCD is carried out. Andsimulation outputs like time limit for the project, pouring intension, efficiency of theequipments are analyzed.Thirdly, comparison and optimization of the RCD construction schemes isdiscussed in the paper. Optimization for pour dividing rooms of RCD and mechanicalequipment coordination is studied. And methods of project completion probability arediscussed.Fourthly, the ways to realize the visualization of RCD construction process ispresented and discussed. The 3D dynamic visualization for construction of JinanqiaoRCD is realized in the form of 3D animation, which provides an impactful means toanalysis the whole construction process intuitionticly.Finally, practical developing way for construction simulation and optimizationsystem of Jinanqiao RCD is presented, and the systematic structure is designed. Witha new design pattern based on component/framework, the DAMSIM_JAQ system isdeveloped by OOM and VC++. The system provides a useful analysis tool tounderstand the complex construction system and makes the construction organizationdesign more scientifically.
