Construction method of anti-floating anchor rod in complex karst development area based on BIM (Building Information Modeling)

The invention discloses a construction method of an anti-floating anchor rod in a complex karst development area based on BIM, and belongs to the field of construction of the anti-floating anchor rod, and the construction method comprises the following specific steps: (1) collecting related information to construct each group of engineering models; (2) designing anchor point positions to construct each group of anchor rod models; (3) performing cascade analysis on the matching degree of the karst position and the drilling model; (4) feeding back each group of generated data to the management platform for checking; (5) optimizing the performance of the management platform and analyzing and detecting the log data of the management platform; according to the method, the number of the anchor rod can be automatically given, the length of the anchor rod can be finely determined under the condition that the bedrock surface of the complex karst area fluctuates greatly, the matching degree of the karst position and th
