description The invention discloses an arch dam safety evaluation method based on a geomechanical model comprehensive method testThe method comprises the following steps: S1, building a comprehensive method testsafety evaluation index system according to detected data; s2, constructing an abrupt change model for evaluating the safety degree of the arch dam; s3, standardizing each underlying index of the comprehensive method test, and converting the underlying indexes into dimensionless data between 0 and 1; s4, performing mutation level calculation by using a normalization formula, and solving a total mutation level value of the target layer; s5, repeating the steps S1-S4, respectively calculating arch dam safety total abrupt change level values under different overload coefficients in the comprehensive method test, drawing a relation curve graph of the total abrupt change level values and the overload coefficients, and obtaining a high arch dam comprehensive method test safety coefficient according to inflection points
