In this study, based on data from instrumentation Kaboodval earth dam, pore pressure, stresses and the meeting of the dam construction period compared with the values ​​of numerical analysis. For this purpose, during the construction of the dam using Mohr-Coulomb model behavior, the softening, hardening model has been analyzed and pore pressure, stresses in the body and its meeting with instrumentation data is compared. According to consistent data and analysis instrumentation, can be selected behavioral model able to predict reservoir behavior is appropriate at this stage. All three models also show good agreement with instrumentation data, but hardening model has provided a better agreement. Basically hardening model because it considers more parameters of the soil, the model behavior of the material better. The amount of Ru is less than 40/0. The highest value of this index actually happened 90-91 years, especially due to the reasons for impounding reservoir and dam load (fill embankment dam), respectively. Taken together, these ranges are within the allowable range. تفاصيل المقالة

In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the comparison is accurate. Choose materials as main materials behavioral model of elastic-plastic materials and filter housings and follow the model of linear elastic behavior for injection layer, properly able to predict the behavior of the dam. The efficiency of the software used to model the appropriate behavior is the embankment dam during construction. Vertical deformations of the dam from the wings to the middle levels increased and the highest-level meeting 25-25 and about 2200 mm has been recorded. By examining the different levels, the highest-level meeting between 180 to 185 meters has occurred. The balance of the embankment in these numbers is critical. The major concerns in the elderly is limited barrier. In total, the dam Figures on the right than the left in the transverse and longitudinal direction less was more. تفاصيل المقالة

The seepage and slope stability are very important and necessary in the dam dirt are, therefore, in this context, numerous applications to predict and calculate the rate of leakage has been prepared that than the experimental time and cost savings for the analysis of liquids before construction of earth dams need. In this study, safety factors for slope stability software Kaboodwal plaxis two-dimensional dam during and end of construction, filling, fast and slow decline in the tank and the tank was half full review. Using software Plaxis upstream and downstream slope stability was obtained for the various stages of construction. The results indicate dam slope stability in various stages of construction and above all in the end stage of construction. Generally, analysis, appropriate behavior dam structures against static and quasi-static loading conditions the authors write. Confidence by increasing the height of embankments have reduced in the last stage of the embankment number is 498/1. By comparing the results at the end of the build confidence slope stability criteria Army Corps of Engineers ensured America. Evaluation of slope stability, slope instability upstream near the tank shows that the need for concrete in this area is evident. And the efficiency of the method and software used to model the behavior of embankment dam during construction is suitable. تفاصيل المقالة
