问:水文地质普查工作中如何确定含水岩层的富水性?答:水文地质普查工作中最重要的任务之一,就是根据野外测绘和勘探资料对含水岩层的富水性作出正确的评价。一般情况下含水岩层的富水性,根据钻孔的最大可能涌水量(Qmax)作为衡量标准。因为钻孔涌水量往往受到抽水设备能力的限制,不能代表含水层的真正涌水量;而单位涌水量在含水岩层变化比较复杂的
Q: How to determine the water-richness of aquifers in the hydrogeological census? A: One of the most important tasks in the hydrogeological census is to correctly evaluate the water-richness of the aquifer based on field mapping and exploration data. Under normal conditions, the water-rich of aquifers is measured according to the maximum possible water inflow (Qmax) of the borehole. Because the borehole water inflow is often limited by the capacity of the pumping equipment, it can not represent the true water inflow of the aquifer; while the water inflow of the unit changes more complicatedly in the aquifer
