Abstract
This paper presents an analysis of excavation behavior of an earth retaining wall supported by large diameter soil-cement blocks at a field trial site. The concept and design philosophy of the large soil-cement block reinforcement are described first. The wall behavior during sequential excavations up to 9.8 m is analyzed based on the measured lateral wall movements and earth pressures. The settlements of adjacent ground are examined by field measurements and inverse numerical analysis. The results indicate that, when the lengths of the soil-cement blocks were over 0.45 H (H: wall height), the displacements and the earth pressures induced by the excavations were similar to those supported by conventional methods such as soil nailing.
