Mechanically stabilized earth (MSE) walls are being widely used for building reliable and economic retaining systems. A full-scale MSE wall was constructed and monitored in a residential compound in New Cairo, Egypt, to evaluate the performance of MSE wall designed using the Simplified method [1, 2]. The wall is 4.4-m high, reinforced with high-density polyethylene (HDPE) geogrid, and its facing consists of modular concrete blocks. Field monitoring was conducted through strain gauges attached to 4 reinforcement layers, and surveying of wall facing using total station device. Strain gauges measurements were used to evaluate local strains along the geogrid layers; while the total station measurements were used to estimate the global horizontal displacement of the wall. Field monitoring data were recorded at the end of construction and after applying additional loads on top of the wall of approximately 20kPa and 40kPa. Brief summary on installation of the monitoring instrumentation is presented. Only two out of 168 strain gauges were damaged during the construction and monitoring durations, which indicated that the followed installation and protection techniques were effective. Constant rate-of-strain (CRS) tensile laboratory tests were conducted to characterize the geogrid stiffness and to evaluate correction factors required to account for the ratio of global to local strains (at strain gages). A strain rate of 0.05%/min resulted in adequate correction factors. The probable zone of failure was determined based on the location of maximum recorded strains within the wall mass, which matched Rankin's theoretical failure plane. Maximum measured horizontal displacements from strain gauges measurements and wall face surveying occurred at approximately 40% of wall height from wall base. Generally, recorded data herein matched well with data reported in the literature for similar MSE wall configurations.
