摘要
在深入研究现有土壤入渗参数推求方法的基础上 ,提出了推求土壤入渗参数的改进Esfandiari法 ,在数据计算方法上将 Esfandiari方法的寻优计算改为直接计算 ,减少了计算次数 ,提高了计算效率。实例计算表明 ,改进 Esfandiari法的计算、试验工作量小 ,其入渗参数的推求结果与现有的几种方法的推求结果接近。
Based on the indepth study of the estimation method for the existing soil infiltration parameters, this paper presents the improved Esfandiari’s method for the estimation of soil infiltration parameters. In data calculation method, the search for the optimalization calculation of Esfandiari’s method is changed into the direct calculation, thus, reducing the numbers of calculations and raising the calculation efficiency. The results from practical example calculations indicate that the calculation tests by the improved Esfandiari method require small amount of work, whose estimated results from the infiltration parameters are found to be close to the estimated results by the existing several kinds of methods.
