摘　　要：通过水力学模型试验,研究确定了金沙江向家坝水电站截流戗堤的布置、龙口位置的选择、龙口段和非龙口段的划分、截流水力学参数和施工进占抛投方式,尤其对围堰残埂及岩埂对截流的影响进行了比较研究,为截流施工方案的决策和实施提供了科学的依据。Hydraulic model test is conducted to study and determine location of river closure dike, selection of river closure gap location, division of gap section and non - gap section, river closure hy- draulic parameters and dike material throwing patterns. Especially, alternative studies that the impact of the residual - dyke of cofferdam which provides scientific basis for decision and implementation of river closure construction scheme.
