摘　　要：根据北濠闸2006年3～7月调水试验资料，分别利用现行水闸设计规范中的两种算法计算了北濠闸泄流能力，并与实测泄流量比较。结果表明，两种算法计算值都有一定程度的偏差，算法1计算值偏大，算法2计算值偏小，取两者平均值作为泄流量精度较高。建议在条件许可时应做水闸调水试验，并结合物理模型试验最终确定合适的水闸泄流能力。The discharge capacity of the Beihao water gate is calculated using two formulas of the present design specification for water gate and the measured hydrologic data, which was accumulated in water diversion experiment at Beijiaowet tidal plain water network area from March to July of 2006, and the calculated discharges are compared with the measured discharges. The calculated discharge values using the two formulas have some error. The discharge flows calculated by the first formula are overvalued, while the calculated data using the second formula are normally undervalued, and the mean values obtained by the two formulas have more high precision. Our suggestion is that whenever conditions are allowed the discharge experiment of water gate should be taken, and the final discharge capacity of water gate is determined with the consideration of the result from physical model test.
