Outline of Final Research Achievements

The specimen for triaxial compression test is made with drying-wetting cycles under one-dimensional compressive stress. The triaxial compression test result showed that the strength of the specimen is decreased by drying- wetting cycles. The specimen’s grain size before and after drying-wetting was almost same. However, the grain is softened by drying-wetting. From the above, the reason for the strength degradation is the grain softening in dry-wetting cycle.
The effective seismic countermeasures for mudstone embankment is different from the embankment form. However, slope protection is effective seismic countermeasures for every embankment form in this study. The slope protection embankment deformation of top of slope is one-third of the non-countermeasure embankment deformation. However, the reinforcing material is yielded by the earthquake.
