本文根据漫滩水流的运动特点，将漫滩水流的复式断面分为主槽平衡区、滩槽交互区、滩地平衡区及边壁区等4个区，并给出了各区宽度的经验公式.根据滩槽交互区垂线流速分布的变化特点，提出了附加尾流函数的对数流速分布公式.在简化水流运动方程和泥沙扩散方程的基础上，对滩槽交互区内垂线平均流速及含沙量沿横向分布进行了理论分析，提出了反映滩槽水流动量交换强度的横向涡量粘性系数及横向扩散系数的表达式，得到了漫滩水流垂线平均流速及含沙量沿横向分布的解析解，并与实测资料吻合较好 - Through checking computations , it was shown that the analogue accuracy of the model was quite high , which can provide important basis for scientific decision - making on engineering measures . through analogue calculation and analysis of many regulation schemes , it was shown that combining the diversion weir works with the bed fixing works at the south branch is reasonable and feasible in the implementation of loushuikouzi river regulation works . in addition , it is suggested that the bed fixing works at the south branch should adopt the improved compound section scheme
