Revetment project is characterized by long coastline distance,multiple project divisions,complex slope protection types,and large bank slope variation,and has problems such as inaccurate calculation of engineering quantities and tedious construction details.In view of the above problems,we complete the creation and editing of terrain surface,3D model of slope protection,engineering quantity calculation,and earthwork calculation based on the BIM concept,taking Ma'anshan river bank revetment project as an example,and using software such as Civil 3D,subassembly composer,InfraWorks,and the application of BIM+GIS,and form a set of application processes of BIM technology for the revetment regualtion.The research results may serve as reference for similar project construction.
