| Outline of Final Research Achievements |
To improve geo-structure technique for tsunami countermeasures, 1) modeling of tsunami-load for structural design, 2) investigation of the optimum geometry to reduce tsunami energy, 3) verification of the geogrid-gabion method for erosion control and 4) development of risk-based design for geosynthetic reinforced soil structure were performed. Following mail results were obtained. 1) New load model was built using over 6000 survey data after the Tohoku earthquake in 2011. 2) Structure having slope face for coastal side and vertical face for land side is most effective to reduce tsunami energy. 3) Geogrid-gabion method is useful for erosion control. 4) Accuracy in calculation of the failure of probability for risk based design was improved for geosynthetics reinforced soil structures. These achievements contribute for reasonable counter measure using geo-technology for tsunami.
