摘要
截潜工程是解决枯水期河流断流不能满足正常设计要求的常用措施之一,如何合理确定截潜引水工程的位置具有十分重要的理论与实际意义。在拟定截潜引水工程区水文地质模型和边界条件的基础上,运用数值模拟的方法,对河南省郏县广阔渠截潜引水工程区渗流场特征进行了研究。研究表明:截潜工程实施后,从截潜流量,截潜所引起的盐渍化、沼泽化及社会影响等方面综合考虑,方案二的截潜效果优于方案一,这一结论为截潜引水工程的位置选择提供了理论依据。
Interception project is a useful measure to guarantee the discharge in the dry season. Hence, the determination of the location of interception project is of great theoretical and practical significance. Based on the hydrological model and boundary conditions, numerical simulation method is used to study the seep- age characteristics of interception project area. The results show that if the project implemented, considering the intercepting seepage discharge and some negative influences, the second interception program will be better than the first program. This conclusion provides a theoretical basis for choosing the location for the interception project.
