| 摘 要： | 利用有限单元法进行二维水质模拟不用考虑河流速度和流量分布等资料,可以直接根据河床地形特点求出水质分布.但传统方法需要利用作图法求出累积流量曲线,是整个模拟过程中最耗人力物力的过程.为解决这一问题,探讨了拉格朗日插值法在复杂河段二维水质模型数值计算中的应用,运用该方法对三峡长寿段的排污口对干流影响进行了数值计算,并将计算结果与作图法的结果进行了比较,比较结果验证了该方法具有省时、高效的优点,具有更加广阔的应用前景. |

| Abstract: | Without considering the river flow velocity and flow rate distribution, the finite element method can be used to solve the water quality distribution directly by river basin characteristics. Accumulative flow curve can be solved by grapgical construction traditionaly,but this method must cost a mass of energy and time.This paper discussed the application of Lagrange Interpolation in numerical simulation of two-dimensional complicated river sections. Through numerical calculation of the influences of wastewater drainage in three gorges reservoir on Changshou section, and comparison between the graphical construction and interpolation, the feasibility and advantages of this method were verified. |
| Keywords: | interpolation numerical simulation two-dimensional river |
