The design, construction, and first-year performance of an experimental tire-anchored timber retaining wall constructed with salvaged materials are described. The tire-anchored timber wall is an extension of previous research by the California Department of Transportation in which tire sidewalls were used to reinforce embankments. Two walls were constructed in August 1981 on CA-203 at Mammoth Lakes, California. They consisted of used railroad ties for facing supported by embedded tire sidewall and steel tie-back anchor assemblies. Wall heights varied from 3 to 12 ft with a 1.5:1 sloping backfill. One wall was instrumented to monitor stresses in the anchor bars and horizontal and vertical movements of the face. The walls are performing satisfactorily after one winter season that included an earthquake that measured 5.8 Richter local magnitude. No visual damage or increases in anchor bar stress were sustained or recorded even though ground accelerations at the site were estimated to be between 0.2 and 0.3g. The tire anchor walls were constructed at a bid price of $22/sq ft compared with conventional concrete retaining walls proposed for the same sites, which were estimated at $50/sq ft. The performance of these prototype tire-anchored walls has exceeded all expectations. The cost-saving advantages of this system have created considerable interest, and several walls of this type are proposed for rural locations in California. (Author)
