Research On Construction Quality Management Of Bridge Engineering Based On BIM Tech Nology ——A Case Study Of The Wudongde-Hemenkou Bridge Project

Traditional quality management mode is difficult to meet the needs of bridge construction quality management because of its low information level,difficult information sharing and coordination,low visualization degree,and BIM Technology can make up for the above defects due to its technical characteristics.But at present,the management practice of BIM Technology in bridge engineering construction quality is still in the primary stage of exploration.The bridge of Wudongde-Hemenkou is a few projects in China and has been carrying out BIM construction quality management earlier.Therefore,the analysis of BIM construction quality management cases of Wudongde-Hemenkou bridge is helpful to improve the BIM construction quality management mode of bridge engineering in China.Combined with the author’s work,this paper first summarizes and introduces the quality management theory,BIM basic theory and BIM application research and exploratory factor analysis method in PDCA quality management.Secondly,according to the five factors（4M1E）affecting the quality of the project,the author analyzes 16 sub factors that affect the construction quality management of bridge engineering,and through the development of bridge engineering construction quality management based on the investigation of the current situation,the paper summarizes the main problems in the construction quality management of bridge engineering,and selects the top 8 influencing factors with the greatest influence,including incomplete joint review of drawings,lack of attention to the summary of quality management promotion,timely handling of quality events,systematic file management,timely quality acceptance,nonstandard filling of construction log,and technical analysis The technical disclosure is not thorough and the material tracking is unclear;thirdly,according to these eight key factors,combined with the four links of PDCA implementation of the Wudongde-Hemenkou bridge,two typical bridge BIM construction quality management activities are selected for each link to carry out case investigation,and the implementation results are summarized;finally,Suggestions on BIM construction quality management of bridge engineering are put forward.The research of this paper not only deepens the theory of bridge engineering quality management,but also provides reference for BIM construction quality management practice of similar projects.
