[目的]研究土地整理中机井水位降深的测算方法。[方法]根据抽水试验资料,作出机井水位降深和出水量的关系曲线,得到计算水位降深的经验公式,并通过实例进行说明。[结果]降深h与流量Q关系曲线的类型主要有直线型、抛物线型、指数曲线型和对数曲线型等,可用图解法和差分法来判断曲线类型;实例计算结果说明,图解法和差分法的计算结果较为接近。[结论]由抽水试验资料建立的经验公式,反映了机井水位降深和出水量之间的相关关系,是合符实际的有效方法。
[Objective] The research aimed to study the method of calculating the drawdown of machine well in land consolidation. [Method] Based on the pumping test data, the relationship between the drawdown of water table and the water discharge was made. The empirical formula for calculating the water depth was obtained and illustrated by examples. [Result] The curves of the relationship between the depth of fall and the flow rate, Q, were mainly linear, parabolic, exponential and logarithmic. The types of curves were determined by the method of plotting and the difference method. Difference method calculation results are more similar. [Conclusion] The empirical formula established by the pumping test data reflects the correlation between the drawdown of water table and the water discharge, which is an effective and practical method.
