概略地测定井、钻孔等地下水的涌水量,一般是量出地下水的静止水位,然后用抽水工具抽水,使水位下降到一定深度,停止抽水;使水位恢复到原来高度,记录水位恢复时间,按下式计算涌水量,Q=w/t=f×s/t式中:Q=井或钻孔的涌水量;W=出 Roughly measuring the inflow of groundwater, such as wells and boreholes, is generally to measure the still water level of the groundwater. Then pumping the water with a pumping tool to lower the water level to a certain depth and stop pumped water. The water level is restored to the original level, the water level recovery time is recorded, According to the formula to calculate the amount of water inflow, Q = w / t = f × s / t Where: Q = wells or borehole water inflow; W =
