초록
In this study, the large scale test was performed to investigate the behavior of failure for the embankment and spillway transitionalzone by overtopping. The pore water pressure, earth pressure, settlement and failure pattern of covering embankment with geotextilewere compared and analyzed. The pore water pressure showed a small change in the spillway transition zone and core, indicating thatthe geotextile efficiently reinforced the embankment. The earth pressure decreased the infiltration of the pore water only in inclinedcores type to secure local stability. The behavior of failure started from the bottom and gradually progressed upwards. After theintermediate overtopping period (100 min), width and depth of the seepage erosion were very small due to the effect of geotextilewhich delayed failure. Therefore, the reinforced method by geotxtile was a very effective method to respond to the emergency dueto overtopping.
