“影响半径”是水文地质勘察中一个重要参数。它的测定方法——多孔或单孔抽水试验,涉及野外工作量的大小,它的应用关系到地下水资源评价的准确性。经过二十多年的生产实践,不少单位发现“影响半径”的测定方法计算公式和应用上都存在不少问题。
“Radius of influence ” is an important parameter in hydrogeological survey. Its measurement method - porous or single-hole pumping test, involving the size of the field workload, its application relates to the accuracy of groundwater resources assessment. After more than 20 years of production practice, many units have found that there are many problems in the calculation formula and application of the measurement method of “influence radius”.
