确定渗透系数的地下水位计试验法

Testing Method of Groundwater Level Gauge for Determination of the Permeability Coefficient

以摆纪磷石膏堆场为例,应用空压机对磷石膏含水层进行提水试验,采用地下水位计方法求解磷石膏渗透系数。实例研究表明,结果与室内试验一致,且该方法求解简单、速度快、精度高,既适用于潜水含水层渗透系数的求解,又可推广到承压含水层渗透系数的求解,有着较好的实际应用价值。

The article takes phosphogypsum field in BaiJi as an example, application of phosphogypsum air compressor to carry on water aquifer tests. The groundwater table methods is used to solve phosphogypsum permeability coefficient. A case study shows that the method has rapid speed, high accuracy and the results consistent with the laboratory test. It also can be used for both confined aquifer and unconfined aquifer, so it has important praetieal value for seientifie research and engineering praetiee.
