영문 초록

During an embankment is affected by a tidal fluctation, as to the variation of the free surface into the structures, it take place the behavior of the embankment, reduce it's stability. The outside of the embankment which influenced by the tidal fluctation divided into saturated, saturated-nonsaturated, and nonsaturated domain. This paper analyzes the free surface into the embankment as to the regular variation of water level, and the use of an experimental model show these phenomena. The results are as follows: 1) H₂=O(cm): In the seepage phenomena of the boundary between K₁ and K₂domain, the height of free surface is high in KL domain, when water level rising and the height of free surface is heigh in K₂domain when water level descending. 2) H2=40(cm): In the seepage phenomena of the boundary between K₁ and K₂ domain, the height of the free surface is high in K₂ domain when water level rising, of dropping. Especially the djfference is larger for the draw-down. 3) H₂ =2O(cm) : i) H₁< H₂: The free surface now from the interior to exterior of an embankment, when water level rising, or dropping. ⅱ) H₁> H₂: The free surface flow from the exterior to the interior of an embankment, when water level rising, or dropping. ⅲ) H₁=H₂: The phenomena of the hysterics is appear In between the water and the soil particles.
