涌水量与降深曲线类型的判别及求参程序

Discrimination of water inflow-drawdown curves and establishment of parameter program

利用涌水量与水位降深关系曲线解决水文地质问题,关键在于曲线类型的正确判断。笔者认为曲线类型的判别以相关系数衡之为佳,为克服手工计算繁琐且精度低的缺点,我们以 BASIC 语言编制了判型求参程序,在PC-1500机上实算通过,经实际应用效果良好,通常需以天为单位的工作量,计算机仅在弹指之间可告结束。该程序具有实用意义。

In the hydrogeological calculation,the correct discrimination of water inflow-drawdown curves is very important to solve some hydrogeological problems and practically the accuracy of curve-fitting.The correlation coefficient can play a important role for the discrimination of curve type.To overcome the short- age of complicated calculation and low precision of manual operation,the authors prepare a new parameter program by BASIC language on PC-1500 computer.Then,new program is applied to practical calculation. The fitting accuracy of power function between the water inflow and drawdown curve is higher than that of old program and the calculation time taken by the computer is faster than the time taken by the manual opera- tion.It shows that the parameter program is characterized by perfect performance,high use value,simple op- eration and good generality.
