Behavior of Pore Water Pressure and the Present Status of Agricultural Reservoir due to Raising Embankment in Korea

摘要

This study was carried out to safety evaluation, the practical applicationand the present status of agricultural reservoir due to raisingembankment. The seepage analysis and large-scale model for inclinedcore and vertical core type embankment were performed to compareand analyze the pore water pressure (PWP), leakage quantity,settlement and piping phenomenon. In the seepage analysis, generally,the stability for piping phenomenon after raising embankmentincreased stable state in comparison with before raising embankment.In the model test, on the whole, the vertical core type is morevulnerable to infiltration than the incline core type.
