| In this paper,the author imitate 3D model of underground plant of Sanbanxi and its cavities with the method of immobile mesh & virtual flux of node. Several difficulties,caused by the variety of stratum structure, the special seepage controlling measures and the complex plant structure are solved. The complex seepage field of underground plant of Sanbanxi is computed successfully. The advantage of improving on calculation precision by draining substructure is fully certificated. |
