摘　　要：万家寨水利枢纽位于黄河中游,其库区狭窄多弯,由于河道断面宽度和河床比降变化大等特殊地形条件,每年进入冬季的封开河关键期容易形成冰塞、冰坝,出现凌汛灾害。对万家寨库区1998年以来近15年的冰情资料进行分析,并对库区的冰凌进行测量,分析总结库区段流凌期、封冻期和开河期的凌情特征及变化,以制定出更好的防凌方案。Wanjiazhai Water Multi-purpose Dam Project locates in the middle reaches of Yellow River which forms a narrow and multi-bending reservoir. Because of the special terrain conditions of narrow water surface and large river channel slope in Wanjiazhai Reservoir, the ice damming and ice flood disasters are easy to be appeared in ice freezing and thaw period in winter. The ice data in past 15 years since 1998 in Wanjiazhai Reservoir are analyzed and the ice conditions in river are investigated. The ice regimes in the periods of ice-run, freezing and thaw are analyzed respectively to make a better ice flood control scheme.
