Research Topics
We have studied effective and efficient methodologies for reliability-based analysis and demonstrated their applicability to civil engineering practice. We have also studied mechanical behavior of gematerials through experimental apprach.
Reliability-based anaysis for geotechnical structures
|
In geotechncial designs, several types of uncertainties are needed to be considered because they can strongly impact on structural safety. In this study, we have developed reliability-based design methods and applied to geotechncial design practice. |

Inverse analysis in civil engineering: Geophysical tomography
|
Reconstructing images of grounds through geophysical tomography is a typical inverse problem. In civil engineering practice, available observation data are very limited, and the inverse problems tend to be "underdetermined (ill-posed) problems." We have developed inverse analysis methods designed to solve underdetermined problems based on the methodologies in statistical mathematics and evaluated their performances. |

Numerical simulation for large deformation behavior of geomaterials
|
We have developed numerical methods for simulating large deformation and failure behavior of geomaterials based on discrete particle methods. |
