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。
On the basis of further study on the existing methods for estimating soil infiltration parameters, an improved Esfandiari method for estimating soil infiltration parameters is proposed. The calculation method of the Esfandiari method is changed from the optimization calculation to the direct calculation, which reduces the calculation times and increases The calculation of efficiency. The example calculation shows that the calculation of Esfandiari method is improved, and the experimental work is small. The estimation results of the infiltration parameters are close to those of the existing methods.
