| Research Abstract |
In order to study the mechanism of slope failure of river banks during heavy rainfall and flooding and to propose appropriate and definite measures to prevent these damages, some centrifuge model tests and numerical analyses were conducted in this project. Centrifuge tests were done by considering various situations associated with the dimensions and material properties of banks, the strength of rainfalls and the rate of water rise by flooding. The influential factors on slope instability due to saturation and softening of fill materials were fully examined together with the results of numerical analyses, and the mechanism of bank failure was broken down to discuss and propose definite measures against these damages.
