The invention relates to a method for analyzing and processing turnout curves. The method comprises the following steps: judging standard fault curves in a turnout curve polling and calling standard fault curve database one by one; if the standard fault curves conform to a standard fault result, displaying the fault content; if no fault is found during the polling of all the standard fault curves, calling a non-standard fault experience database; if non-standard fault curves which are matched with the current curves are directly found in the non-standard fault experience database, determining that the current curves have the faults; if the current curves cannot be matched with the non-standard fault curves in the non-standard fault experience database, and cannot be matched with the standard curves at the same time, determining that the curves have a novel fault type; and storing the current curves in the non-standard fault experience database. The accuracy of the standard fault curve database of the method is higher, but the application range is narrower; while the accuracy of the non-standard fault experience database is not very high, but the non-standard fault experience database can judge whether the curves have the faults or not within a wider range, and the accuracy and the wider range. The standard fault curve database and the non-standard fault experience database complement each other to achieve high efficiency.
