Physical modeling of the filtration process through the dam base

Abstract

In this article, the results of model studies to determine the value of filtration in different soil layers that form the foundation of the dam for different filling of the reservoir are given and empirical dependences of the filtration level on the amount of filling of the reservoir are given. When conducting research and evaluating the ongoing filtration processes at the dam base, experimental research methods were used using well-known principles of physical modeling on a specially modeled hydraulic model unit. When analyzing the results of experimental studies, methods of mathematical statistics were applied and graphical and empirical dependences were obtained showing the relationship between the pressure in front of the dam and the filtration pressure at the base of the dam. Under the conditions of the physical model, for different filling of the reservoir, the filtration values in different soil layers composing the dam base are determined and empirical dependences of the filtration level on the reservoir filling are obtained.
