Abstract :

The first thing that is vital in the modern embankment dams Construction, it is the correct and monitoring of the geotechniqual constructions. From the experimental results in this work is determination of rules that can help us in performing of the future works. Now, it is considered that inverted analysis method is a very useful tool for understanding the behavior of dam in the hand of engineeres. By investigation of data and using inverted deciding in construction of dams.     In this paper monitoring of Mahabad dams With using acculate tools information and numerical analytic has considered. In performing of numerical analytic, it is used by Geo Slope Software package that is a analytic software base on finite element method. By helping in convey of data and performing inverted analysis, condition of Mahabad embankment dams has analysed. While it is more than thirty years form the dams, in the beginning of the construction of this dam, has considered the unusul settlements and horizontal displacements. As foundation settlement up to ending of performing operation (from 1344 to 1348), has measured 125 cm and during exploitation (from 1349 to 1376), has measured 70 cm. From the time of construction, the maximum settlement and horizontal displacement are measured 140 cm and 110 cm respectively. After construction cutoff walls and finishing operation injection in foundation of dam, rate of seepage from foundation is decreased too and according to the numerical calculations in negligible extent is (0.04 centimeter cube in minute) and rate of seepage in body dam is (7.5 centimeter cube in minute).
