一 概述 在水文地质勘察中,计算集水井涌水量的公式,可分为,一为理论公式(如裘布依公式),一为涌水量经验公式。在采用经验公式时,首先根据抽水试验资料(一般为三次降深)确定曲线方程的类型,其次在已确定曲线方程类型的基础上,确定方程中的参数。方程类型及参数确定后,即可建立相关方程式,继而根据建立的相关方程式-经验公式,预测一定降深条件下的出水量或一定出水量条件下的降深值。本文仅就PC-1500计算机对完成前两项工作的过程介绍如下。
An overview of the hydrogeological investigation, calculation of catchment water inflow of the formula can be divided into, a theoretical formula (such as fabric according to the formula), an influx empirical formula. When empirical formulas are used, the type of the curve equation is first determined based on the pumping test data (typically three drawdowns), and secondly, the parameters in the equation are determined based on the type of the curve equation established. After the type and parameters of the equation are determined, the relevant equation can be established, and then according to the established formula - empirical formula to predict the depth of water under a certain depth conditions or a certain amount of water under the conditions of value. This article only on the PC-1500 computer to complete the first two processes are described below.
