应用匀坡及加坡原理,推导出了单井(孔)稳定流承压完整井渗透系数的计算公式,该公式已考虑到无效降深对渗透系数计算的影响,同时在计算过程中充分利用了水位恢复资料,而水位恢复的过程也排除了一些干扰因素的影响,因此,参数计算结果应更接近实际。
By using the uniform hydraulic gradient and variable hydraulic gradient principle
a computational formula of permeability coefficient of the single well(drillhole) steady flow confined fully penetrating well is derived
in which the effect of noneffective drawdown on permeability coefficient is considered
and the most of water level recovery data in computational process are used
while some interference factors effect is excluded in the water level recovery. Therefore
the parameter calculation will still approximate to the fact.
