초록
In this study, an experiment with large-scale model was performed according to raising the embankment in order to investigatethe behavior of failure for embankment and spillway transitional zone due to overtopping. The pore water pressure, earth pressure,settlement and failure pattern by a rapid drawdown and overtopping were compared and analyzed. The pore water pressure and earthpressure at spillway transitional zone by overtopping increased a rapidly with the expansion of seepage erosion, but the crest showeda smally change due to effect of the inclined core type. And it is considered an useful data that can accurately estimate the possibilityof failure of the reservoirs. A settlement at overtopping decreased a rapidly due to failure of crest. The relative settlement differencedue to change of the water level at the upstream and downstream slope cause increase largely crack of crest. The behavior of failureby overtopping was gradually enlarged towards reservoirs crest from the bottom of the spillway transition zone, the inclined core afterthe raising the embankment was influenced significantly to prevent the seepage erosion.
Abstract
In this study, an experiment with large-scale model was performed according to raising the embankment in order to investigatethe behavior of failure for embankment and spillway transitional zone due to overtopping. The pore water pressure, earth pressure,settlement and failure pattern by a rapid drawdown and overtopping were compared and analyzed. The pore water pressure and earthpressure at spillway transitional zone by overtopping increased a rapidly with the expansion of seepage erosion, but the crest showeda smally change due to effect of the inclined core type. And it is considered an useful data that can accurately estimate the possibilityof failure of the reservoirs. A settlement at overtopping decreased a rapidly due to failure of crest. The relative settlement differencedue to change of the water level at the upstream and downstream slope cause increase largely crack of crest. The behavior of failureby overtopping was gradually enlarged towards reservoirs crest from the bottom of the spillway transition zone, the inclined core afterthe raising the embankment was influenced significantly to prevent the seepage erosion.
