Abstract：Scarcity in boreholes data formed by bad break, caused by faults broking the continuity of strata, and the disposing of the bad break in 3D geological mode (3DGM) at present, a new method based on generalized triprism (GTP), named as local virtual modeling borehole (LVMB) was put forward. The main steps of this method include:①To judge two limit triangle, which need insert LVMB between them; ②To insert LVMB to the corresponding two edges of up and down limit triangles automatically;③To construct the strata between the two limit triangle. The test shows that the LVMB method can create 3D model of bad break inside geological body automatically, the created model is more correct than other method at present, so the applied scope of GTP volume for 3DGM is extended.
