Tanque verde retaining wall structure: Revisited after 11+ years
Between December 1984 and September 1985, 46 concrete panel retaining walls were constructed using structural geogrids of polyethylene to create grade separations for a transportation intersection in Tucson, Arizona. During construction, select panel walls were instrumented to measure temperature, lateral and vertical soil pressures, and strains in the geogrid. The combination of elevated temperature and aggressive soil exposure and aging, while under stress, make this particular project a focal point of continued investigation. Geogrid samples retrieved from this project in September 1993 and again in June 1996 were evaluated and compared to an archived sample from the same production run. Wall instrumentation, which has been monitored from 1985 to 1992, was most recently monitored in June 1996 to evaluate the mechanical stability of these walls. Instrumentation readings and results from evaluation of the physical and mechanical properties of the exhumed geogrid samples are presented in this paper. It is concluded from testing of exhumed samples, after 11 + years of exposure, that the polyethylene geogrid has not experienced any measurable change in its physical or mechanical performance properties, nor has the wall been compromised in its stability or performance.
