Abstract
Recently the instrumentation of dams has gained a special place in Iran. In large-scale projects, such as earthen and concrete dams, instrumentation installation and monitoring, especially during the construction and operation, is an integral and essential component. Dam stability is one of the most important issues related to geotechnical engineering. Therefore, considering the uncertainty of geotechnical parameters,risk analyses are inevitable in dam projects. This study has first examined the accuracy of the instrumentation installed in the dam, then dealt with the quantification of the maximum settlement, vertical stress in the core, and arching phenomenon based on the results of numerical analysis and instrumentation.For numerical analyses, theGeoStudio 7.1 Software was used. In addition to simultaneous analyses, this software is also capable of analyzing the stage construction and two-dimensional consolidation. Behavioral models used in the analysis consist of linear-elastic and elastic-perfectly plastic Mohr-Coulomb models. Acomparison between modeling and concise instrument results suggests that the doostidam is in a stable and safety condition.
