| Abstract: | In major flood season of 2005,the embankment dam in the subsection of Dalong Key Water Control Project under construction was directly attacked by the typhoon Dawei. The rainstorm continuously fell in the drainage area. The maximum peak flood flow into reservoir is 9 950 m3/s. The mass rising water level in the front of dam was 34.4 m. The partial piping phenomenon burst out at the section of embankment dam in the flood season of construction. The embankment dam was successfully withstood with the ordeal of... |
