A geological 3D modeling method of comprehensive geological section for Chengdu

Comprehensive geological section is an important source of data for geological 3D modeling. Building geological 3D model by using comprehensive geological section is widely used in areas with complex geological settings. Taking Chengdu as an example, this paper introduces in detail the geological data to be collected for the construction of comprehensive geological profile, the deployment principle and construction method of the profile, and solving the problem of connection between different strata of the same age and horizon in the process of profile construction. Practice shows that the construction of comprehensive geological section can give full play to the subjective initiative of geologists in geological 3D modeling, accurately depict the distribution of complex geological bodies in 3D space, and improve the efficiency and accuracy of geological 3D modeling.
