Research On Application Of Inland River High-pile Wharf Design Based On "BIM+GIS" Technology

Building Information Modeling(BIM)technology has three-dimensional(3D)and design parametric modeling capability.It can integrate 3D engineering environment and design project and also can be combined with GIS technology to achieve lightweight delivery of BIM and further application of BIM.In recent years,the competent departments of the transportation industry have successively issued documents requesting to strengthen the application of BIM in design and construction,and to promote the development of "BIM+GIS" technology.At present,the application of BIM in water transportation engineering design is still very insufficient.The dock plan involved environmental information such as surrounding pipe network,roads,buildings.The environmental condition is complex and including in hydraulics land and loading and unloading technology.The majors are frequently crossed.The traditional two-dimensional design plan has a long time and a long iteration of the plan.Many designs change a lot.Based on “BIM+GIS” to carry out research on the plan of the wharf engineering,it can reduce the number of plan changes to a certain extent and improve the quality of the plan and the efficiency of communication.Based on the engineering example of Luoqi Port in Chongqing City,this paper carries out the design and application research of inland river high-piled wharf with "BIM+GIS" technology.The main research work and conclusions of the thesis are as follows:(1)Among the major platforms of BIM,based on the complexity of the high-piled wharf of water transport engineering,the article focus on research and analysis of the four mainstream platforms in China,and compare and analyze their respective characteristics.Combining with the particularity of inland river high-piled wharf,the Bentley platform with wide range,professional functions and strong modeling ability is selected(2)Individual build terrain and real scene models with rich environmental details quickly.Based on routes and terrain files,people conduct 3D parametric collaborative modeling design for each specialty of the terminal.Use renderings,roaming packages,VR and other methods for visual interaction and program comparison.The feasibility of BIM model and finite element model conversion is discussed to realize the high-precision conversion from BIM model to structural calculation model,ensure the consistency of calculation model and design model,and improve the iterative efficiency of "design calculation optimization" structural design.(3)Through the integration of BIM and open source GIS technology,the "BIM+GIS" digital platform is researched and analyzed,and the visual analysis of design results and cloud delivery applications are constructed.Realize remote interaction,program comparison and selection,and BIM lightweight functions,so that traditional design results and BIM results can be visually integrated.The combination of BIM structural calculation model and ABAQUS is established to realize the high-precision conversion from BIM model to structural calculation model,ensure the consistency between calculation model and design model,and improve the iterative efficiency of "design calculation optimization".(4)Analysis of BIM application and implementation mode of water transport engineering,according to the current status of the water transport terminal industry.The main problems hindering the development of BIM application are analyzed,and the implementation mode,process and strategy of BIM in the whole life cycle are put forward,which provide a basis for industry BIM development.
