摘要
为探寻基于地下水对洪水响应的含水层水力参数反演方法,引进卷积分和优化技术计算含水层的压力传导系数和河床沉积物的阻滞系数,提出了基于Excel的反演计算流程,利用Excel实现了卷积分计算和参数求解。以陕西省榆林地区补浪河为研究区,开展了地下水对洪水响应的含水层参数反演,并与抽水试验确定的含水层水力参数进行了对比验证。结果表明,提出的方法与抽水试验方法计算的含水层的水力参数相差17%,可满足实际工作的需要。
In order to explore the method that could calculate aquifer hydraulic parameters using the groundwater response to flood,the convolution and optimization technique were introduced to calculate aquifer diffusivity and river resistance. This paper presented the Excel-based calculation procedures and used Excel to calculate the convolution and parameters. It carried out flood wave tests in the Bulang River in the Yulin area of Shaanxi,calculated aquifer hydraulic parameters using the flood wave method,and compared with the parameters derived from pumping tests. The comparison shows that the difference is about 17% ,which can meet the demand of practical work.
