Research on BIM application in urban rail transit station and yard drainage
To improve the design quality of urban rail transit station and yard drainage,reasonably reduce engineering investment,effectively improve design efficiency and achieve digital intelligent design,a drainage design system for urban rail transit station and yard is researched and developed based on BIM technology.The system could carry out the design work by linking the horizontal and vertical viewports,constructing the surrounding environment model of the yard and depot,and creating the parameterized family library of drainage ditch.According to the design model of the rail operation area roadbed and the design model of the yard apron,the system uses the principle of streamflow simulation to automatically identify the catchment compartment of each drainage ditch,evaluate its drainage capacity,and efficiently complete the three-dimensional design of station and yard drainage.The research shows that the multi-dimensional information characteristic of BIM model could provide support for automatic and accurate definition of catchment compartment and assessment of drainage capacity,thereby significantly improves the design quality.The reference to parametric drainage ditch family library greatly simplifies the modeling and design process,and effectively promotes the digital intelligent transformation of urban rail transit station and yard.
