This paper presents a case history of culvert sections used as a retaining wall. The wall discussed in this report was one of two built in 1974 on the Marys Peak Road in the Siuslaw National Forest, 20 miles west of Corvallis, Oregon. Both were constructed over relatively weak foundations and were designed to accept a high degree of differential settlement. The tallest of the two was 40 feet high, 150 feet long, and it supports a 32 foot high rock fill surcharge. The other wall is 350 feet long with a maximum height of 14 feet and directly supports the roadway. The wall facing is made of U-shaped members made from corrugated galvanized sheets (similar to half round culvert pipes). It is held in place by a series of horizontal metal straps which are attached to a continuous metal strap anchor. The wall was instrumented during construction and thus far internal stresses and movements are within design tolerances.
