Abstract:

Considering the importance of dam construction projects and spending high costs to build them, assessment of the authenticity and evaluation of the expected performance ofdams is important for decision-makers. In this article, stability analysis of dam slope of Tanguye Sirjan will be investigated and analyzed by using Geo-Studio software. At first, finite elementsof model were established of the studied attic slope by SIGMA/W program and were analyzedby the stress-strain case Results confirmed the stability of the dam at the end of the construction with an acceptable reliability. Based on the obtained results, reliability in upstream slopes in themodes of normal level, flooding balance and half full tank in static conditions are respectively,2.355, 2. 64 and 2.58. In this way and under the same conditions for the downstream slope, the amounts are respectively, 2.38, .2.39 and 2.38. Based on modeling results in terms of quasistatic, values of reliability for the upstream slope in the normal level balance, flooding balanceand half full tank are equal to 1.4, 1.4 and 1.35 and for downstream slope in same quasi-static conditions and at normal level, flooding balance and half full tank are equal to 1.58, 1.64, 1.637. The results showed that in the condition of rapid drop of Reservoir, the balance of water tank for the upstream slope is equal to 2.52.
