Apparatus and Method for Monitoring Soil Slope Displacement Rate By Detecting Acoustic Emissions

An apparatus for monitoring soil slope displacement rate comprises a sensor (I) beatable on an active waveguide (E) partially buried in the soil to detect acoustic emissions transmitted through the active waveguide (E) as a result of soil displacement. The monitoring apparatus also includes a processor arrangement which analyses the detected acoustic emissions to determine a ring down count rate, compares the determined ring down count rate with a predetermined trigger value, and generates an alert when the determined ring down count rate exceeds the predetermined trigger value. There is a predetermined relationship between ring down count rate and soil slope displacement rate and the ring down count rate thus provides a direct indication of the soil slope displacement rate.; The processor may also be operable to determine the rate of change of the ring down count rate, and hence the soil slope displacement rate, and to generate an alert when the rate of change exceeds a predetermined trigger value.
