The fault interpretation method based on the combination of profile interaction and construction pattern guidance as claimed in claim 1, wherein in the step 6), the construction pattern library established in the step 3) is used as prior information to construct a combination relationship between classical construction pattern template constraints in the pattern library and faults on the guidance profile, and the concrete contents include:
firstly, fixing the longitudinal and transverse proportion of section display, comparing the existing main section layer combination pattern in a window with the classic pattern in a construction pattern library window by window, and preferably selecting the classic pattern with the highest matching degree as an expected pattern;
secondly, correcting the cutting and combination relation of main faults on the section based on the expected pattern;
and adjusting the actually interpreted fault pattern according to the overlapping relation and the pattern form of the expected fault pattern, so that the difference between the actually interpreted fault pattern and the expected fault pattern is minimized, and the implementation of the section fault layer combination is completed.
