摘要
基于辐射井抽水降落曲面的数学模型,考虑辐射管数和管长对出水量的干扰作用,建立了单层辐射管均匀布设的辐射井出水量计算模型,进行实例验证,并与等效大井法计算结果对比分析。结果表明,模型计算结果与实测数据吻合较好,精度高,优于等效大井法,可用于出水量计算。
Based on curved surface model of the pumping descent and considering the disturbing effects of the number and length of the radiant tube on water output, the water output model of the whole radiation well of single radiant tube with uniform distribution was constructed, and the model was verified according to the experimental case and was compared with equivalent large-mouth-shaped well method. The results indicated that the calculated values of the model coincided to the measured data with higher accuracy, the model was superior to equivalent large-mouth-shaped well method and the method could be used to calculate the water output.
