Linear engineering slope operation safety risk assessment method

The invention discloses a linear engineering slope operation safety risk assessment method, and relates to the technical field of geotechnical engineering and engineering geology. The method is based on a slope complete data set of linear engineering such as a highway and a railway, firstly, data sample risk evaluation factors are analyzed and determined according to core expert experience, and then normal operation slope data, defect disease slope data and historical disaster slope data are integrated to serve as a slope safety risk training data sample set; and marking the safety risk level of the training data sample by adopting an expert fuzzy analytic hierarchy process (FAHP), and finally constructing a slope safety risk assessment model by adopting a BP artificial neural network method. The evaluation model supports supplement, modification and perfection of a slope sample data set, expands acquisition of slope safety risk evaluation training sample data mainly based on normal slope data, breaks through
