内容記述 |
In this study, the effects of rainfall after an earthquake on the infiltration characteristics and stability of highway embankment structures were experimentally evaluated. A scale model of a highway embankment was used in the test, and nine cases were set with the initial density of the embankment (degree of compaction, Dc) and the degree of damage caused by seismic motion (settlement of crest, ds) as variables. The rainfall intensity was set at 40 mm/h, and data such as water pressure head, hw during rainfall, and the time of occurrence of slope deformation, tf, were collected. As a result of the test, in the case of high-density embankment with Dc = 90%, the number of cracks increased as ds increased due to vibration, and the time when hw began to rise was shortened. On the other hand, in the low-density embankment with Dc = 85%, the density of the embankment increased after the earthquake, and the permeability coefficient decreased, which suppressed rainfall infiltration. The relationship between the number of cracks, nc, after the shaking and the rate of increase in hw per unit time, dhw/dt, showed that dhw/dt also increased as nc increased. |
