Abstract

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.
