Abstract

 During the 2011 off the Pacific Coast of Tohoku Earthquake, a lot of houses were suffered severe damage due to the open crack of ground and the differential ground settlement around the boundary area of cut-and-fill in the filled-valley residential site. The ground deformation around the boundary area of cut-and-fill in the filled-valley residential site is influenced by the shape of old ground surface. Then, the measurement of 3-D residual displacement in the model ground is necessary to study the soil deformation mechanism in the filled-valley residential site. In this note, the measurement method of 3-D residual deformation by using the multi-layered color sand grid is proposed. This method made it possible to indicate the internal 3-D residual displacement in the model ground.
