结合工程实际建立了下土寨分水闸三维造型，根据水力学理论进行相关边界条件设定，同时对不同来流条件及闸门开度下的下土寨分水闸流场进行三维流动水深模拟分析。结果表明，三种工况下水深的模拟结果与相关资料吻合度均符合工程要求，后两个工况结果有部分出入的主要原因是模型建立时对分水闸前后延伸的距离简化所致。该模型的求解可为该工程段的设计提供理论参考，也可为类似的工程设计提供借鉴。

The 3D modelling is established in combination with the engineering practice ,by referring to the theory of hydraulics to set relevant boundary conditions .For Xiatuzhai distribution structure the three‐dimensional flow field is analysised to simulate the flow depth under different flow condition and gate open‐ing .The results show that under three kinds of working conditions the simulation results of water depth are in agreement with related data ,meeting the requirements of the project ;The discrepancy for the latter two kinds of working conditions is mainly due to the simplification in the extended distance before and after the distribution structure .The solving of the model can provide theoretical reference for engineering design of the project ,also can provide reference for similar engineering design .
