Abstract

In case of large-scaled bridge foundation of soft rocks such as weathered granite, it is important to evaluate deformation characteristics of bed rock properly for predicting deformation and rational foundation design. As the results of underground displacement measurement during construction, the authors have made to conclude as following points. In the range of the rock mass classification D_H and C_L at the survey point, <br>(1) The deformation characteristics depends on the strain level in the shallower zone.<br>(2) Whichever the rock mass classification, the deformation characteristics depend on the restrain in the deeper zone.<br>(3) The deformation characteristics depends on the large-scaled excavation in the near surface zone.
