Abstract

Studies of seismic response of reinforced soil systems have largely focused on failure mechanisms. However, design requires demonstration that deformations are tolerable. To investigate the serviceability of a soil nailed wall, a centrifuge testing program was conducted. Model walls were constructed, and then subjected to three successive earthquake motions to determine their deformation under seismic loading. Models represented a prototype excavation of a 12 m deep wall with five rows of nails at a scale factor of 50. This paper summarizes the scaling considerations, the model preparation procedure and the method used to perform the tests. In addition, the result of a test on the nailed wall is presented through which the pattern of wall deformation and changes in the tensile load of an instrumented nail during the earthquake motions are reported and discussed.
