Study On Simulation Method Of Bridge Construction Schedule Based On BIM Model

With the increasing scale of bridge engineering,construction requirements are getting higher and higher,the traditional construction schedule management methods can not meet the current bridge construction requirements.The emergence of BIM technology provides a new way to improve the efficiency of bridge construction schedule management.At present,the application of BIM technology in the construction schedule management of bridge engineering is still in the exploratory stage,especially in China,and the application case is still relatively small,and the research direction is mainly focused on the three-dimensional visualization of the model,the real value of BIM is not fully exploited.Therefore,the paper systematically studies the construction schedule management method of bridge engineering based on BIM technology.On the basis of summarizing the existing methods of bridge construction schedule management,this paper firstly analyzes the existing problems of the traditional construction schedule management method and puts forward the general idea of introducing BIM technology for schedule management.Secondly,the method of BIM technology applied to bridge construction schedule management is discussed.Then,by comparing the advantages and disadvantages of multiple BIM core modeling software and project management software,this paper puts forward a new method of building BIM planning model by using 3D modeling software Revit,project management software Project and simulation software Navisworks.This paper summarizes the advantages of BIM planning model for bridge construction management.At the same time,a real-time model establishment method based on oblique photography is proposed to keep the project managers better grasp the construction situation and make more accurate management decisions for the problems such as the slow collection of data in the current bridge construction schedule field.Finally,based on the actual bridge engineering case,the BIM planning model of the bridge engineering is established by BIM technology,the construction schedule simulation is carried out,and the construction schedule prediction method is discussed preliminarily.This paper provides a more systematic way for BIM technology to be used in the construction schedule management of bridge engineering,which can provide reference for the application and development of BIM technology in more fields.
