摘　　要：为了保证利泽航运枢纽修建阶段航道能够保证基本的安全通航功能,根据利泽航运枢纽工程施工导截流1:100正态定床物理模型试验的成果,从流速、流态、通航流量以及航行路线等角度分析施工导流期三期的通航水流条件以及围堰截流试验情况,并得出截流时不同龙口宽度的计算参数。结果表明,提出的施工三期导流围堰方案所得出的试验结果在流速、流态等水流条件方面均可较好地解决本枢纽工程的施工期通航问题。To ensure the basic navigation function of the channel during the construction phase of Lize Navigation-Power Junction,according to the results of the 1100 normal fixed bed physical model test for the construction diversion and closure of Lize Navigation-power Junction,we analyze the navigable flow conditions and cofferdam closure test in the third stage of construction diversion period from the perspectives of velocity,flow pattern,navigable flow and navigation route,and obtain the calculation parameters of different closure widths.The results show that the test results obtained from the proposed diversion cofferdam scheme for the third phase of construction can well solve the navigation problem during the construction period of this navigation-power junction in terms of flow velocity,flow pattern and other water conditions.
