单孔稳定流抽水试验计算渗透系数对比研究
|
摘要
在水文地质普查阶段,为了解预查研究区含水层的富水性、地下水类型和渗透系数,以防城港地区那梭镇ZK03号水文地质钻孔作为主要研究对象,根据钻孔水文地质条件和工作条件,采用单孔稳定流抽水试验的方法对那梭ZK03号水文钻孔进行3次降深的抽水试验,根据涌水量、单位涌水量与降深之间的关系曲线图,可以确定该地下水埋藏条件为承压水,容积法可大致确定抽水井出水量约为1.81L/s,为中等富水性。按稳定流计算通过迭代法、水文恢复法对比计算分析可以得出水文恢复法计算的渗透系数值较为合理,更具有可参考价值,为下一步评价含水层特性与地下水资源评价提供依据。
In the hydrogeological survey phase,in order to understand the water aboundance,groundwater type and permeability coefficient of the aquifer in the study area,the paper took the hydrogeological borehole of ZK03 in Nasuo town in Fangcheng port area as the main research object. According to the borehole hydrogeological and working conditions,the water pumping test of the ZK03 hydrologic borehole was performed three times by using the method of single hole stabilizer. In consideration of the relationship ofthe water inflow,the volume of water and the depth of the water,the groundwater burial condition can be identified as the confined water.The volumetric method can be used to determine that the water flow from pumped well is about 1.81 L/s,being moderately rich. Based on the steady flow,through comparing iteration method and hydrological restore method,it is found that using hydrological restore method to calculate the permeability coefficient value is more reasonable,more worthy for reference,and the results could provide evidences for evaluating the characteristics of aquifer and groundwater resources.
