对三峡工程截流戗堤坍塌作了分析，提出了对策。
2.
Through hydraulic model test,we determined the time interval and means of river closure,and the arrangement of closure dike.
通过水工模型试验研究,确定截流时段、截流方式及戗堤的布置,探明截流龙口水力特性,合理选择龙口位置及宽度,为截流施工方案的决策和实施提供了科学的依据。
3) double embankments
双戗堤
1.
A judging method of river closure with double embankments is put forward.
计算双戗堤立堵截流龙口水力要素时,提出用非恒定流计算方法求解戗堤间恒定流动时的水面线,分析龙口流速变化规律,研究上戗堤、下戗堤进占时截流落差分配之间的关系,降低上戗堤合龙难度,提出相应的双戗堤截流优越性判断方法。
