Holographic method for analyzing stability safety of side slope

The present invention discloses a holographic method for analyzing stability safety of a side slope, and data obtained by using the method is accurate and comprehensive. The holographic method for analyzing stability safety of a side slope comprises the steps of: (1) for a position whose slide-in point and slide-out point of a sliding surface of a side slope are given, calculating safety coefficients of all sliding surfaces under a designated sliding mechanism and/or a constraint condition; and (2) by using an optimization method, finding a sliding surface having a minimum safety coefficient among all the sliding surfaces that are under the designated sliding mechanism and/or constraint condition and that pass the slide-in point and the slide-out point.
