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 ...
the design of appropriate, cost-effective remedial measures requires a clear understanding of the processes that are causing the landslide. this understanding require a detailed site investigation, a reconnaissance of the landslide as soon as possible after it's occurrence can allow important observations of the processes involved. a key step in analyses of soil slope stability is measurin...
Abstract In the paper numerical modelling of ensuring slope stability and their analysing with using different methods are presented. We have designed cutting walls earth nails anchors securing for ensuring. The calculate mechanism failure process reinforced slopes were studied stability. nailing significantly increased level Spencer method. Increasing nail or length improved slopes. exhibited ...
in the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. in 2-d analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...
A practical procedure is described for implementing Spencer’s method of slices with varying side force inclination. The search for the noncircular critical slip surface is accomplished using spreadsheet-automated constrained optimization. The deterministic formulation is then extended probabilistically to compute the Hasofer-Lind reliability index via constrained optimization of the dispersion ...
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...
