电法勘探在常德市松散孔隙含水层中涌水量预测的应用

Application of Electric Prospecting to the Prognosis of Water Yield of Loose Pored Aquifers in Changde City

常德市水文地质及电测深、电测井的资料反映了孔隙水含水层涌水量的大小与含水层厚度、颗粒组分及其结构的多因素的复杂组合──—厚度（Ｍ）与视电阻率（ρ＿ｓ）的乘积密切相关，据此可预测单井涌水量。

The electrical sounding and logging as well as the hydrogeological data in Changde city indicated that the water yield capacity is closely related to the product of the thickness(M)multiplying the apparent resis-tivity(ρ_s), which is a complicated combination of many factors including the thickness, the grain composition and the texture of the aquifer.It can be based to estimate the water yield capacity of single well。
