An ambankment and an unstable natural slope were monitored by using AE monitoring and traditional field techniques. AE characteristics of the two slopes were different. Results from the embankment showed that the period of AE occurrence approximately coincides with the movement of the embankment. In the natural slope, significant increases in levels of AE count rate were recorded at least two months before the observation of detectable ground movement. In the prediction of slope failure, it is… CONTINUE READING
