The application discloses a kind of based on BIM
software's foundation pit external corner anchor rod drilling optimization method, comprising the following steps: step one, Revit
software is opened to make nested parameterized anchor rod family file;Step two, load family file in step one, and make foundation pit external corner support model according to design drawing;Step three, start
Dynamo software, open program script one and run, check the collision of each row of anchor rod of foundation pit external corner, and export collision data;Step four, export data after step three, if there is collision, automatically mode program script two is run in
Dynamo software, the inclination angle of drilling is optimized, and the inclination data after optimization is exported;Step five, after the maximum value of inclination after step four is optimized, still have collision, automatically mode program script three is run in
Dynamo software, drilling hole position is optimized, and the hole position data after optimization is exported.The application can effectively guarantee the safety and stability of foundation pit
support system.
