For the traditional waterway regulation engineering problems,such as the inadequacy of two-dimensional design accuracy,the hasty scheme research time,the tedious and error-prone statistics of engineering quantity,etc.,taking the second stage of waterway regulation of the Xinzhou to Jiujiang section of the middle reaches of the Yangtze River as an example,this paper introduces BIM technology,expounds the waterway engineering BIM 3D modeling technology,and the 3D collaborative design of the whole section.The application characteristics of BIM technology in the design of channel regulation engineering are summarized,and the three-dimensional visualization,parameterization,synergy and intelligent design of the channel project are realized,so that the design process is optimized,and the precision of design is improved.
