Simulation method of kink structure

The invention provides a method for simulating a kink structure. The method comprises the following steps that a two-dimensional geologic body section model is constructed, the two-dimensional geologic body section comprises a plurality of mutually parallel rock stratums, and first joints and second joints which penetrate through the geologic body section along the thickness direction of the rock stratums and are mutually parallel; a kink belt clamped between the first joint and the second joint rotates integrally under lateral extrusion, and rock stratums in the kink belt slide relatively; the hanging disc part and the footwall part on the two sides of the kink belt slide and rotate in the direction opposite to the rotating direction of the kink belt due to rotation and sliding of the rock stratum in the kink belt, and relative sliding occurs between the rock stratums of the hanging disc part and between the rock stratums of the footwall part. The method is advantaged in that the method can be used for discu
