| 摘 要： | 相比理论公式法，基于最小二乘法原理及其计算方法，结合MATLAB数值分析软件对抽水试验数据进行曲线拟合，求得拟合公式，同时得Q—sw关系曲线的计算和绘制转化为计算机来处理，避免了手工绘制和计算求解时存在的各种人为缺陷；公式能够对勘探孔的Q—sw关系进行定性定量的分析，降低误差因素影响，提高预报流量的可信度。

| Abstract: | Compared with the theoretical formula,the fitting formula can be obtained through the curve fitting to the pumping test data by means of the numerical analysis software with MATLAB on the basis of the least square principle and its calculation method.The fitting formula could be used to analyze the Q-sw relationship between exploratory hole qualitatively and quanlitatively,reduce the influence of error factor and improve the credibility of the flow prediction,and provide a reliable scientific and rational b... |
