Abstract:

Three active landslides located in Eagle County, Colorado, were monitored with an acoustic emission (AE) recording device for an 8-month period beginning in January 1985. AE monitoring devices are used to detect the transient elastic waves generated by the release of energy within a material undergoing failure. The slides were also instrumented with groundwater observation wells and inclinometer boreholes. Groundwater data and displacement measurements gathered from these devices and data collected from surface movement observations were correlated with the AE data. Significant increases in levels of AE activity were recorded at least 30 days before the observation of movement at each of the slides. Rises in groundwater levels recorded at many of the observation stations appear to have triggered the slides. AE signals recorded after the initial failure of the slides correlated with the rates of movement measured at surface displacement observation stations. This study has successfully demonstrated the ability of a properly installed AE monitoring system to detect premovement stresses in soil slopes. AE can be used as an early warning system to reduce hazards to life and property on high-risk soil slopes, road cuts, tailings dumps, dams, foundations, and other civil structures.
