Research On Design Method Of Large Water Level Difference Overhead Vertical Wharf Based On BIM Technology

With the vigorous development of information technology,all walks of life has ushered in tremendous changes,especially industry,electronic information and other industries,of which the application of information technology has become a new direction for the development of construction projects.With the help of computer,BIM(Building Information Modeling)has promoted the development of information application of construction engineering.The application of BIM technology is also being explored in the field of water transport infrastructure.The application and research of BIM technology in large water level difference overhead vertical wharf is in the initial stage,there are many problems,such as immaturity of design method,lack of corresponding standards and specifications,and incompact combination with finite element calculation.Based on BIM technology,this paper will explore and study the design method of large water level differential overhead vertical wharf.In order to meet the requirements of large water level difference overhead vertical Wharf Multilayer cable,the hydraulic structure part is usually set as frame structure,which makes the multi-layer contact support crisscross and complex structure.Combining with the complexity of the structure,and comparing and analyzing the advantages and disadvantages between several BIM design platforms,the Autodesk platform is selected as the design foundation.Combining with the parametric characteristics of BIM technology,the method of parametric design of component is studied under the aid of Revit of core modeling software,and the parametric family library of large water level differential overhead wharf is established,and the construction method of the whole BIM model of large water level differential overhead wharf is studied by using the components in this family library.Based on a practical project,the research of structural finite element calculation,secondary development and so on is carried out.Firstly,based on the structural analysis module of Revit software,this paper studies the method of structural analysis model creation of this engineering example,links the analysis model to the finite element structure calculation software Robot which is closely related to Revit,and this paper introduces the calculation method of Robot in detail.Secondly,the problem of data interaction between Revit's structural analysis model and the large general finite element structure computing software ANSYS is studied.In addition,the paper also studies the secondary development of Revit,extracts various information data of BIM model through API interface,and explores the deep application of BIM model.Through the above research work,this paper can draw the following conclusions: Autodesk platform is suitable for BIM technology application of large water level differential overhead wharf,and the parametric family Library is established;the solution to the problem of ANSYS and Revit data interaction is provided;the "information" plugin is developed to extract model information;the BIM design flow for large water level difference overhead vertical wharf is summarized.In addition,through literature analysis,practice inquiry and other means,this paper discusses the problem of information loss in the application of BIM technology in the whole life cycle,then it introduces the IFC Standard of BIM data exchange Standard.
