Considering the excavation process and the complex geological conditions in metro station construction,a BIM data-driven general scheme for geological stratum identification and station enclosure structure feature recognition is pro-posed with Revit secondary development.Using Delaunay triangulation and inverse distance weighted interpolation meth-od,parameterized generation and management of boreholes and strata are realized.Considering different calculation re-quirements,structured data processing and calculation output are carried out and an integrated platform is established.Thus,a standardized and intelligent fine calculation process for earthwork of metro stations is achieved.Compared to tra-ditional calculation methods,the efficiency and accuracy are both improved.
