Abstract:J. Erik Loehr ; orcid.org/0000-0001-6035-8416 ; An instrumentation and monitoring system was implemented for a geosynthetic reinforced soil (GRS) integrated bridge ; system (IBS) constructed in Boone County, Missouri in 2014. The project location is subjected to relatively frequent flash ; flooding, which was a significant consideration in the design of the bridge and the design of the monitoring system. The ; monitoring system includes 26 surveying points on the bridge exterior to monitor external movement; settlement plates and ; inclinometers to monitor vertical and horizontal exterior movement, respectively; earth pressure cells to monitor total ; stresses within the abutment backfill; and vibrating wire piezometers to monitor pore pressures and drainage within the ; abutment backfill. The GRS-IBS was monitored for a period of 19 months after construction. The monitoring period ; included several high-water events, but none overtopped the bridge. The results indicate satisfactory performance, ; including negligible external and internal movements and rapid backfill drainage in response to groundwater level ; increases.
