LONG TERM PERFORMANCE OF THE FIRST REINFORCED EARTH WALL IN CALIFORNIA

This final report presents the long term performance of the first reinforced earth wall constructed by Caltrans in 1972. Field instrumentation since 1974 has indicated a continuing outward movement of the wall face at the south flank which has been documented in previous reports. Various remedial measures have since been instituted to improve wall stability. These are presented herein along with performance data. Final instrumentation measurements for this study were made in May 1980. They suggest continuing increases in train of embedded reinforcing strips. Some significant reductions in strain rates have occurred since completion of additional buttressing and embankment reshaping. It is assumed that the embankment and foundation system is still readjusting to remedial measures. A condition survey in June 1980 revealed that the overall appearance of this facility is good. Future performance will be monitored as required. (FHWA)
