Power transformation engineering multistage slope modeling method based on BIM technology

The invention relates to a power transformation engineering multistage slope modeling method based on a BIM technology. The power transformation engineering multistage slope modeling method comprisesthe following steps: step 1, creating a digital terrain according to original measurement data; step 2, creating a sloping path on the digital terrain; step 3, creating a multi-stage side slope component; step 4, assembling the created multi-stage side slope components; and step 5, generating a multistage sloping model. According to the method, based on the digital terrain generated by Civil 3D discrete measurement elevation data, a component editor (SubAssembly Composer) is utilized to create multistage slope components including slope design parameters, logic rules of excavation and fill judgment and slope termination boundary conditions, and a multistage slope three-dimensional model is quickly generated. By means of the method, slope ratio, slope height, riding track width, riding track height and other slopin
