摘　　要：运用通航水力学及通航船模试验相结合的方法，综合分析了戗堤预进占口门宽度与口门区通航问题，从试验角度论证了预进占口门宽度能满足二期截流施工期长航船队通航要求。By means of navigation hydraulics and voyage tests with radio-controlled barge models, the problems of proper width between the pre-advanced banquettes and of navigation through the gap are analyzed comprehensively. It is proved that the width between the two pre-advanced banquettes can meet the requirements which are needed for the YNRMB's barge tow to navigate through during river closure. The rationalization of the width between the banquettes presented by designer, is also demonstrated.
