  • Stability of Quay Wall under Back Rush of Overflow Tsunami

説明

In this research, the stability of the quay is examined by hydraulic model experiments at the time of the back rush of overflow tsunami. As a result, by taking earth pressure in back into consideration, it makes clear that the collapse phenomenon of a quay is a slide due to water level difference between front and rear side of a quay. The value of pressure of front side, which is in contact with the rubble ground, has dispersion. This dispersion has influenced stability of a quay and it is producing variation in failure of a quay. Moreover, in order to abolish the variation in the pressure, when it verified using the front water level, it turned out that stability is verifiable to a safe side. In the range of this experiment, it is possible to verify the stability of a quay by applying this assumption.
