| Outline of Final Research Achievements |
Mechanical properties and the applicability for road pavement and coastal protection of soil block produced by cement-mixing and mechanical dehydration are evaluated. In addition, this study proposes a formula to calculate the stable weight of soil block underneath breakwater foundation in consideration of the overflow and seepage flow induced by tsunami based on the theoretical force balance between frictional resistance of soil block, the tractive force of the water flow over the caisson to the soil block and seepage force thorough underneath breakwater foundation. A series of hydraulic model experiments were conducted on the scale of 1/100 for Kamaishi Bay breakwaters as the subject in order to confirm the effectiveness of the proposed formula. Using the test results, the stability of the soil block underneath breakwater foundation was evaluated from the geotechnical engineering point of view as well as the hydrodynamical point of view.
