Abstract

After several years of operation, there is a discrepancy between the measured data from the piezometric pipes and the initial design infiltration line of the dam. A mathematical model can be established to infer the permeability characteristics of the rock and soil materials in the earth dam based on actual boundary conditions such as upstream and downstream during the operation. This allows for a re-evaluation of the seepage safety of the dam. Taking a dam in Anhui Province, China as an example, the infiltration coefficient of the downstream dam material of the reservoir dam was found to have an increasing trend based on the inferred data from field measurements after several years of operation. It is recommended to continue strengthening monitoring and analysis of this dam.
