土木学会論文集B2(海岸工学), 72(2) I_919-I_924, Nov, 2017 Peer-reviewed This study deals with the process that tsunami flow on land collides with a vertical wall. A tip of the tsunami flow collides with the wall and runs up along the wall and then the water column collapses on the following tsunami flow. In this study, the characteristics of the tsunami impact force on the wall caused by splashdown of the run-up water column were experimentally investigated. From the measurement of the pressure synchronized with the high speed video images, it was found that the local maximum values of the pressure were caused by splashing down of the water column. We assumed this phenomenon was casting up of the water column and then freely falling on the following flow. On the basis of this assumption, the elapsed time from the collision to the splashdown can be explained by using the maximum depth of the passing tsunami flow. The pressure distributions were not a static pressure profile when the local maximum pressure was caused by splashdown of the water column.

28TH INTERNATIONAL CONGRESS ON HIGH-SPEED IMAGING AND PHOTONICS, 7126 ICHSIPS28, 2009The authors applied an ultra-high-speed video camera to visualize crack propagation in brittle bodies, such as mortar specimens, under the impact splitting test. Strain of the brittle bodies in impact splitting tests was analyzed by means of PIV (Particle Image Velocimtery), which is usually used for measurements of flow fields with tracer particles. The results show that, when the applied impulse on the mortar specimens is increased, the crack propagation velocity reaches an upper bound. The upper bound of the crack propagation velocity was 2.6 km/sec. The horizontal tensile strain around the crack tip was estimated to be 370 mu by PIV measurement with the ultra-high-speed camera, and 270 375 mu by strain gages, respectively. Those results showed a good agreement with each other.
