| Outline of Final Research Achievements |
(1)We proposed some equations of probability on slope collapse during strong earthquake based on the slope damages during the 1995 Kobe, the 2004 Chuetsu, the 2014 Kamishiro fault and the 2016 Kumamoto earthquakes, as well as the road disaster prevention check data. We indicated the validation for the isolated areas assessment in the southern Wakayama and the northern Nagano by using the results of statistical analysis for the relationship between the slope damage probability and the road damage.
(2)We conducted twice field surveys at Aratozawa where one of the largest landslide in Japan occurred during the 2008 Iwate-Miyagi inland earthquake, and laboratory tests of the soil and the rock samples. Based on the test results, we performed three dimensional Smoothed Particle Hydrodynamics analyses for the landslide. We also improved the methodologies of time integration and damping calculation for analytical stability and accuracy.
