自动配线法求水文地质参数的优化路径法研究

摘要

Manual curve-fitting is a method to solve hydrogeologic parameters , but it is very time consu-ming and tedious, and traditional computer curve-fitting is a better method on the other hand that also has shortcomings such as:difficult to operate, require many calculations and lack of visualization .Based on the fact that the standard curve and the measured curve are essentially coincident , a new method of sol-ving hydrogeolgic parameters is put forward to optimize the moving path in which the control points drive all the measured points to move along the standard curve in order to find the minimum value of the sum of squared residuals, the key to this method is to determine the control points , and manual curve-fitting method is used to ensure the results accuracy .This method is verified by some examples which meets the accuracy requirements and at the same time it greatly improves the speed of operations .It has a certain application prospect in the future .%　　针对人工配线法求取水文地质参数费时费力，而传统的计算机配线法存在操作不够简便、后台运算次数过多或缺少直观性的不足，该文基于配线法标准曲线与实测曲线基本重合的特点，采用控制点带动所有实测点沿标准曲线移动，寻找离差平方和最小值的优化路径法求到水文地质参数，提出该方法的关键在于控制点的确定，并补充手动配线法来保证计算的准确性。通过算例验证，新方法在满足精度要求的同时，大大提高了运算的速度，具有一定的应用前景。
