| Research Abstract |
To prevent from a catastrophic collapse of river embankment, and to maintain performance of it during earthquake, a countermeasure was developed. A reinforcement method of wrapping around river embankment by a sheet in combination with conical concrete block and non-woven fabric was studied. This sheet is called ”conical matt”. In addition, to reduce subsidence of the body of embankment, "conical matt" was laid on between embankment and foundation ground. It was clarified that the conical matt was effective for the prevention from collapse and subsidence of embankment, through theshaking table tests and the model test.
