In response to the traditional design issues of restricted waterway revetment engineering in inland rivers，such as lack of intuitive two-dimensional expression，low design efficiency，and complex mapping and calculation processes，this article adopts BIM，GIS，and other technologies for secondary development to form a series of BIM based digital design technologies for revetment engineering.It realizes the optimization of three-dimensional terrain surface interpolation，automatic generation of the front and side lines of the revetment，rapid parameterization creation of revetment engineering models，and mapping and calculation.And relying on the project to carry out technical achievement verification and digital delivery of design achievements，it improves the efficiency of BIM design for revetment engineering，expands the application field of digital intelligence of design achievements，and provides reference for the implementation of digital intelligence work in similar projects.
