Abstract: In order to effectively realize the assessment on healthy status of slopes and failure prediction of diversion projects, a fuzzy evaluation model was constructed to obtain the evaluation affiliation vector of slope status integrating multi-indicator monitored safety information, and then a healthy degree of slope status with higher recognition and more convenient application was proposed; and a prediction method for remaining useful life was established based on the nonlinear Wiener process taking healthy degrees as its performance degradation index; according to calculations of a slope in a water diversion project, the time-dependant healthy degree curve was obtained. The results showed that the method could not only evaluate the healthy status of slopes in diversion projects, but also predict the remaining life, and the prediction accuracy was ideal, which could provide a reliable monitoring method for operation status and preventive maintenance decision-making basis for slopes.
