rodbar dam slope stability analysis using neural networks
در این تحقیق شبکه عصبی مصنوعی برای پیش بینی مقادیر ضریب اطمینان و فاکتور ایمنی بحرانی سدهای خاکی ناهمگن ضمن در نظر گرفتن تاثیر نیروی اینرسی زلزله ارائه شده است. ورودی های مدل شامل ارتفاع سد و زاویه شیب بالا دست، ضریب زلزله، ارتفاع آب، پارامترهای مقاومتی هسته و پوسته و خروجی های آن شامل ضریب اطمینان می شود. مهمترین پارامتر مورد نظر در تحلیل پایداری شیب، بدست آوردن فاکتور ایمنی است. در این تحقیق ...
Multi-Directional 3-D LEM Slope Stability
The limit equilibrium method (LEM) has been a main-stay of analysis for geotechnical engineers for decades. Applied typically in a 2-D plane strain condition the method has been extended in formulation to the method of columns in 3-D and is now gaining increased use in industry. The formulation of the 3-D method of columns has typically been presented in Cartesian coordinates and with the assum...
متن کاملError reduction in slope stability assessment
1. Introduction Slopes in quarries and open pit mines, as well as all the types of embankments (stockpiles, tailing dams, waste dumps) resulting from mining and mineral processing activities, must be considered as "geotechnical structures". Therefore, the design and implementation of these structures must be conducted with all consideration. Considering an economical plan, the selection of reas...
متن کاملSlope Stability Assessment Using Optimization Techniques: an Overview
Slope stability analysis has received increased attention recently. Slope stability problems may be solved using both deterministic and probabilistic approaches and can be characterized as optimization problems. In the deterministic approach, the factor of safety is the function to be minimized, and for probabilistic analysis, the reliability index is considered the objective function. The sear...
متن کاملCombined Hydrology and Slope Stability
by Craig Abram Jordan, M.S. Washington State University Chair: Balasingam Muhunthan Landslides constitute a major geological hazard in the world due to their high financial cost and their nondiscriminatory nature. The Olympic Region of Washington State has many potential triggers of landslides, but prolonged periods of high rainfall is the most commonly attributed trigger of landslides. The cur...
