Embodiment
[0050] Ⅰ. According to the definition of baseline parameters, the underground cavern baseline is generated at one time, and the baseline segments are sequenced and not connected;
[0051] Ⅱ. According to the definition of interface parameters, place the cross-sectional shape at the starting point and end point of each segment of the baseline, and you can choose vertical and vertical two placement methods;
[0052] Ⅲ. Sweep the section along the baseline to generate a solid model of the underground cavern;
[0053] Ⅳ. Carry out Boolean operations (cutting) on the underground cavern entity model according to the geological segmentation modeling method selected by the user;
[0054] Ⅴ. Repeat steps Ⅰ-Ⅳ to sequentially carry out geological segmentation modeling processing for all underground caverns.
[0055] In the above step Ⅰ, the operation of generating the cavern baseline at one time needs special instructions: when the baseline segment is arc-shaped, that is, helical or c...

The invention relates to an underground cavern automatic modeling method based on geology information, and solves the problems that underground cavities and exploration caverns are large in geology information, the multiple geometrical segmented modeling is complex, and the man-machine interactive modeling efficiency is low. The invention adopts the technical scheme that method comprises the following steps: 1, object classification and attribute definition A: the attribute fields are defined for the classified geological objects, and then are outputted in an object classification and attribute definition configuration E; 2, the geometrical parameter input B: a base line parameter definition B1 and a section parameter definition B2 are carried out on the special underground cavities and explosion caverns; and 3, multiple geometrical segmented data input C: according to E, an occurrence geological interface segment C1 and a non-occurrence geological interface segment C2 are carried out according to different classifies of geologic bodies disclosed by the underground cavities and the exploration caverns; and 4, automatic modeling parameterization D. The method is suitable for water conservancy and hydropower, traffic and other engineering practices.
Description
technical field [0001] The invention relates to the technical field of engineering geology and geoscience information processing, in particular to an automatic modeling method for underground caverns based on geological information. It is suitable for water conservancy and hydropower, transportation (subway, tunnel), mining, military and other engineering practices. Background technique [0002] With the development of engineering geology and information technology, a preliminary theory and method system has gradually formed in the information design of engineering geological survey, and the demand for integrated design has been put forward for engineering survey, so that geological analysis can be transformed from two-dimensional analysis to Spanning to three-dimensional space analysis, these changes make geological analysis more intuitive, clearer, and more convenient, and the technical methods and means adopted are also more advanced and diversified. [0003] In engineer...
