Instrumentation of MSE Wall Containing Laterally Loaded Drilled Shafts
Construction, instrumentation, and lateral load testing of eight 0.9m (36in.) diameter columns solely supported by the geogrid-reinforced backfill behind a 6m (20 ft) tall MSE wall was conducted for the Kansas Department of Transportation (KDOT). This paper describes the instrumentation of the wall and the performance of that instrumentation. Instrumentation included 24 pressure cells, 16 inclinometer locations, 112 strain gauges, 20 telltales, 84 photo target locations on the wall facing, and load cells and LVDTs associated with lateral load and response. A detailed discussion of the photogrammetric process used to remotely measure wall deflections through the use of cameras and AutoCAD is presented. A discussion of the relative benefits of the different methods of instrumentation is included.
