基于流速在渠宽方向呈指数分布、水深方向呈对数分布的特点 ,根据流速实测资料 ,利用最小二乘法原理 ,建立了流速和流量公式 ,将各种影响因素概括在两个参数d、f中 ,从而使流量只与最大流速、渠道断面和水深有关。计算流量与试验水槽中标准三角堰实测流量吻合较好。
Based on the exponential distribution of flow velocity in the direction of width and the logarithm distribution of depth in water depth, the flow velocity and flow formula were established based on the measured data of velocity and the principle of least square method. Various influencing factors were summarized in two parameters d, f , So that the flow rate is only related to the maximum flow rate, channel cross section and water depth. The calculated flow rate is in good agreement with the measured flow rate of the standard triangular weir in the test tank.
