| 摘 要： | 为防避四川省北川县白什滑坡坝溃坝酿至溃决洪水与泥石流灾害，对导致漫溢溃坝的水文条件进行了预测。在论述白什滑坡和滑坡坝的特征的基础上，通过对可能发生的溃坝类型、形成漫溢型溃决所需临界水头、溃决时水流流速和导致溃决的洪峰流量的预计，得出了一般洪水时不会溃坝、100年一遇洪水时可能溃坝的预测结论。

| Abstract: | The hydrologic leaded to overflow burst of the Baisha landslide dyke is predicted in order to prevent the burst flood and debris flow. Based on characteristics discussion of the landslide and landslide dyke, the burst type, critical bead of burst with overflow type and flow rate leaded to burst are forecasted. The forecast shows that only the floodwater encountered in 100 years may cause dam break. |
