Long-term behavior of kinevars embankment dam using numerical model and compare it with the Instrumentation results

During the construction and operation of an embankment dam, various parameters, such as total stress, settlement, and most importantly pore pressure in the core affect the dam stability. To study these parameters, numerical modeling of dam behavior in drained or undrained loading and unloading is essential. In this study, the result of instruments in the construction and operation of the Kinevars dam, which include the actual values of stress and settlement is compared with the values obtained from the analysis of stress-settlement achieved from numerical modeling. According to the results, it was found that Geostudio software and Duncan nonlinear elastic model are suitable for analyzing the behavior of an embankment dam. Additionally, our results revealed that the use of simplified common methods for stress-settlement-leakage modeling in dams is reliable. Also, in the construction filling time, the results of numerical modeling and instrumentation for the parameters of pore water pressure and total stress in core are close. Considering the results of this study, it was concluded that the behavior of an embankment dam during construction and operation with acceptable accuracy is predictable by using Geostudio software.
