| 中文摘要: |
| 运用水力学中水渠流量计算方法，对7种不同断面类型的水渠进行数值模拟。比较相同的过水流量下各水渠的优点，得出在相同的过水流量条件下，U型水渠具有占地面积少的优点。数值模拟结果发现不同断面形式的水渠过水量与水位深度呈相关性。使用SPSS统计分析软件推算各类水渠的过水量与水位深度的拟合函数方程，其中梯形断面水渠与U形断面水渠的水流量与水位深度呈一次函数的线性相关，而其它断面水渠呈二次函数的曲线相关。 |

| The numerical simulation on 7 kinds of section of the canal was made by the method of hydraulic caculation for water in the channel.Comparing the advantages of various canals in the same flow,the advantages of less cover of soil surface area of U shape canal is obtained.Within numerical simulation,the results show that flow and water depth of various canals were correlated.The fitting function equations of flow and water depth was calculated by "SPSSS" statistical analysis software.The depth of trapezoidal channel with U-shaped cross section channel flow water level is a function of linear correlation,the other section of the canal is quadratic function curve. |
