3D Visual Modeling Technique for Complex Surface Configuration above Mined-out Regions
It is the premise and base of numerical calculation to build a 3D visual model that reflecting the engineering reality based on representation of land form of engineering geologic body, occurrence of ore-rock and distribution of complex mined-out regions. On the background of MC6 mined-out regions under Yangquan-Yuxian highway, the three-dimension geometry model and mesh are built firstly, through the strong pre-processing capacity of MIDAS/GTS, according to the engineering geological survey data (topographic contour, geologic section, prospect drilling and physical prospecting, and so on); secondly, by the interface program of MIDAS/GTS-FLAC3D complied with MATLAB language, the mesh model built in MIDAS/GTS is imported into FLAC3D, thus the correct 3D visual model of complex mined-out regions is fast built in FLAC3D with high efficiency. The engineering example verifies the feasibility and effectiveness of the coupling method which can provide new thoughts for building three-dimension numerical model for complex engineering.
