Instrumentation and Monitoring for a Riverbank Slope Stabilization Project
A power company is constructing air quality control (AQC) additions at a power plant site in Alabama, USA. The selected location for the AQC additions is near an area that has experienced periodic but regular lateral ground movements. An extensive study was carried out to investigate the magnitude and rate of movements and the factors controlling these movements. A slope stabilization scheme involving construction of one hundred 1.37 meter (m) (54 inch [in.]) diameter drilled shafts adjacent to the AQC additions was implemented to arrest lateral movements. A program of field instrumentation and monitoring was implemented to verify key assumptions during construction, evaluate the effectiveness of the stabilization scheme, and provide information that could be used to modify the stabilization scheme if field observations identified this necessity. Instrumentation included inclinometer casings within selected drilled shafts, inclinometer casings in soil between the shafts and landward of the stabilized area, fiber optic strain gages on shaft reinforcement, standpipe piezometers, and clusters of fiber optic pressure transducers. Data from the instrumentation was collected throughout construction and has proven to be instrumental in evaluating the performance of the stabilization scheme.
