本文从大量钻井抽水试验资料所反映的含水层导水系数(T)与小降深(S<1米)时的单位涌水量(q)之间具有明显线性关系(T=1.30q)出发,结合井群抽水的理论井水位降迭加公式,把半经验半理论的简易水力削减方法,表达成既具有实用精度,又便于确定合理井距、水位下降和水量削减值的简易井群计算形式。 Based on the obvious linear relationship (T = 1.30q) between the water conductivity coefficient (T) of aquifers and the water inflow (q) at small depth of depression (S <1m) Combined with the formula of water level drop and superposition of theoretical well in well group pumping, the simple hydraulic reduction method of semi-empirical semi-theory is expressed as simple well group calculation form with practical accuracy and easy determination of reasonable well spacing, water level drop and water cut value .
