Abstract: Most of the protecting slopes of the reservoir dams constructed in Suihua area in recent years were destroyed by frost action. Based on the investigation of same of the slope, the author considered that the frost heave of the surface of the dam is the primary reason for the damage of the slopes. The different water contents of the slope above and below water level lead the differential frost heave causes the uneven movement of the built body of the slopes,resulting in the damage of the slopes.The ice pressure acting on the dams is another reason for the damage of the slopes.To protect the dams against frost damage, we thickened the sand and gravel-padded layer on the protecting slope of Dongbian reservoir dam. It works well in the past five years.
