Intelligent foundation pit supporting construction method based on BIM technology

The invention discloses an intelligent foundation pit supporting construction method based on a BIM technology. The intelligent foundation pit supporting construction method comprises the steps that an intelligent foundation pit supporting analysis system is established, and a foundation pit supporting parameterized BIM component family library and a database of an intelligent algorithm are built in the intelligent foundation pit supporting analysis system; identifying a foundation pit bottom elevation center line and a geological exploration report geological layer, and performing intelligent analysis; setting basic support parameters; according to the set supporting basic parameters, one-key generation of a supporting structure model, a construction drawing and a detailed statement is carried out; checking whether the generated model meets the requirements or not, and if the model needs to be modified, resetting the model to set the basic parameters of the support until the model meets the requirements; the
