We are working on deformation and failure of rock and rock mass.
"Shear failure" had been paid attention as the fracture mechanism of rock. However, new concepts based on nucleation and growth of microcracks are being formed now.
Studies on the behavior of groundwater and geological discontinuities such as joints and sheetings are also needed to clarify physical property of rock mass.
The results have been applied to the field of underground mining. Recently, we also work on open pit mining, dam foundation, rock slope stability, geological disposal, etc.
If you are interested in our research, please refer to Fujii's page for example.
