    基于镜像法的堤坝拟流场主要物理量分布特征分析

    The study of main physical distribution characteristics of quasi-flowing field in dam by mirror image method

    • 摘要: 拟流场法是探测堤坝渗漏的一种方法,已经得到了广泛应用,但是限于目前对实际堤坝工程拟流场主要物理量分布规律的认知程度,探测过程中有一些“异常”现象还不能给出解释,甚至导致探测结果误判。采用镜像法在理论层面上研究了多介质拟流场,给出了电位、电场强度分布特征,成果丰富了流场法理论,对正确应用拟流场法具有现实意义。

       

      Abstract: The quasi-flowing field method has been widely used for dam leakage detection. However, the distribution features of some main physical variables of the quasi-flowing field in dam and levee project areas are unfamiliar to researchers and engineers. Some abnormal distribution phenomenon of the quasi-flowing field still can not been well explained, or even been explained improperly. In this paper, applying mirror image method, theoretical quantities of two variables with respect to electric potential and electric field intensity in multi-layered media are obtained, and the distribution features of two variables are summarized. The results are helpful to correctly application of the quasi-flowing field method.
