초록
This study aims to evaluate the behavior of poorly-compacted raised reservoir levee with water level raising by using centrifugal model test. From the testresults, it seems that the hydraulic fracturing at the core of the raised reservoir levee with low degree of compaction possibly occurs due to the drasticalincrease of pore water pressure by water level raising. Additionally, the continuous infiltration may induce crack and/or sinkhole on the surface of thepoorly-compacted raised reservoir levee owing to the increase of the subsidences at the crown and the front side of that. Therefore, reasonableconstruction management for the compaction of the raised reservoir levee is needed.
