Research On 3D Visualized Management System For Navigation-Power Junction On Seasonal Frozen River

Navigation-power junctions on Seasonal Frozen Rivers are periodic and discontinuous for the rivers? freezing and thawing which,especially in rainy season,results in more complex construction condition and longer time.To guarantee the construction schedule,several contractors works all at once in the narrow working surface.However,contractors? mutual interference would bring more difficulties to control of the construction.Based on the technology project?The Key Technology and Demonstration of the Dynamic Monitoring of Yilan Navigation-power Junction Project?,this dissertation investigates 3D visualized management system development method for navigation-power junction on seasonal frozen river considering construction feature in seasonal frozen rivers,develop Yilan navigation-power junction dynamic visualization management method,present dynamic simulation and 4D management through the process of navigation-power junction construction,update,classified store,across link and present the mass data,by BIM theory and technologies of GIS,3d Max modeling,SQL database technology and so on.The contents of this research include:(1)Analyze the research status of BIM,engineering visualization and engineering management visualization at home and abroad,elaboratethe basic theory of dynamic visualization,construction scheme dynamic management;Research the influence of frozen river on navigation-power junction,ascertain the aim of 3D visualized management system for navigation-power junction on seasonal frozen river;Build system technology framework.(2)Investigate the construction method of navigation-power junction hydraulic structure based on 3ds Max,GIS and Cityengine;Combined with design datum of Yilan navigation-power junction,conduct 3D panoramic visual simulation of Yilan navigation-power junction.By the means of GIS add-on development technology and C# language,investigate construction dynamic visualized management system and visualized method in report forms and engineering drawings,which solves problems of coupling mass data from different systems.Based on SQL database,study construction method of database;Combined with Yilan navigation-power junction visualization,classify and construct system database,and then ascertain the invoking mechanism of database,design compositive calling mechanismof database.(3)Based on the technology frame of 3D visualized management system for navigation-power junction on seasonal frozen river,combined with construction management experience,system development frame and key technology investigation achievement,research system?s function and relevant function module,solve the problems of dynamic visualization management,construction schedule dynamic management and digitization of construction drawings and report forms.(4)Based on the key technology and function design result,by Visual Studio platform,C# language,combined with data of preliminary design and construction management,develop Yilan navigation-power junction construction 3D dynamic visualization management system,actualize visualized simulation and construction 3D dynamic management of Yilan navigation-power junction construction management.
