Application Of Bim In High Speed Railway Long Bridge Tunnel Group Project

With the rapid development of China's economy and the continuous improvement of information technology,all walks of life are facing tremendous changes.With the rise of Internet of things and smart city,as well as the acceleration of digital city construction,the traditional construction industry urgently needs to realize informatization and digitalization as soon as possible.The concept of building information modeling(BIM)is proposed and introduced,which points out the direction for the traditional construction industry and project management information.Based on the zwcqzq-7 bid section of the new Zhengzhou Wanzhou railway Chongqing section,according to the idea of BIM Technology Application life cycle,starting from the key and difficult points of project construction,this paper analyzes the application requirements of BIM,and then explores the application points according to the requirements,and then elaborates the preparation work,modeling process and application of Bim in management and technology.The results are as follows:(1)According to the life cycle theory of BIM application,a set of BIM Technology Management System,including personnel organization,management system,software and hardware configuration,model establishment and model application,is constructed and analyzed.(2)According to the BIM Technology Management System,the BIM Technology practice is carried out.Through reasonable model division and data processing,the problem that the model volume of long bridge tunnel group is too large and difficult to use is solved;through the modeling attempt and exploration of Revit software and dynamo software,aiming at their characteristics,a set of relatively comprehensive and feasible model establishment methods and parameter setting standards are found.(3)The application of the model is illustrated with examples.The construction management solves the problems of low efficiency of the traditional management mode,and the information storage can not guarantee the quality and quantity of information;the technical management solves a series of technical problems such as the previous paper version disclosure is not intuitive,the disclosure efficiency is low,the construction quality of key and difficult processes is difficult to grasp,the implementation cost of technical improvement and scientific research projects is high and not flexible enough Question.It reflects the advantages of BIM Technology in project construction management and technical management..
