BIM-based fixed-length rock-socketed analysis method for deepwater trestle platform steel pipe piles

The invention discloses a BIM-based fixed-length rock-socketed analysis method for deepwater trestle platform steel pipe piles, and relates to the technical field of constructional engineering.The method comprises the following steps that 1, an investigation design drawing is obtained, and drilling information, drilling positions forming a rock stratum surface and module information of corresponding elevations are extracted from the investigation design drawing; 2, importing the base rock surface information into Civil3D to create a stratum curved surface entity, and exporting a dwg format file; 3, Dynamo is operated to generate a bearing stratum model; 4, creating a BIM model, and combining the geological model to form an analysis model; 5, calculating the length of the pile body and the rock-socketed depth of the built-in section through the analysis model, modifying the pile foundation model and guiding pile foundation construction; and 6, the actual pile length is calculated, a steel pipe pile detailed li
