确定水文地质参数的N次平均降速配线法

CURVE-MATCHING METHOD FOR OBTAINING THEN-TH AVERAGE WATER-TABLE DROP RATE IN DETERMINING HYDROGEOLOGICAL PARAMETERS

摘要:

本文提出的确定水文地质参数的N次平均降速配线法,可用于短期抽水。对于任意观测孔而言,只要有从水位下降算起的两三个小时的抽水资料,就可以采用该方法求得水文地质参数。该方法的标准曲线为弓形曲线,因此,配线时任意性较小,人为影响很小。这在一定程度上保证了参数的精度。

Abstract:

The curve-matching scheme for the nth average water-table drop rate proposed here can be used in short-term pumping. The hydrogeological parameters for any observation borehole can be obtained by this method so long as the pumping data within two to three hours following the water-table drop are available. The standard curve in the method is bow-shaped and incurs little arbitrariness and personal influence during curve-matching, thus guaranteeing the accuracy of the results in a certain extent.
