Determining of Critical Safety Factors for Homogeneous Slopes with Mathematical Model

ERKAN, İbrahim Hakkı | URAY, Esra | TAN, Özcan

In this study, the effect of slope and soil parameters on the slope stability has been investigated. The slope heights, the angle of slope, the weight per unit of volume, the angle of internal friction and the cohesion have been used as the slope and the soil parameters. The parameter levels have been selected according to these values and the critic safety factors have been determined with 1280 analyses. In analyses, Slide computer program has been employed and the critic safety factors have been obtained according to Bishop Method. By using these safety factors, the average Signal/Noise (S/N ...Daha fazlası

Use Of Artificial Neural Networks In Stability Control Of Cantilever Retaining Walls

URAY, Esra | DEMİR, Vahdettin | KESKİN, AslıÜlkü | TAN, Özcan

Stability conditions effective on the design of the wall are safety factors of sliding, overturning and slope stability. Design of a cantilever retaining wall depends on great numbers of parameters such as soil properties and wall dimensions. In addition, design of the cantilever retaining wall must be satisfies stability conditions like safety factors of sliding, overturning and slope stability. It takes time to design wall considered all effective parameters with traditional methods. For this reason, some methods like artificial neural networks have been preferred due to reach the result in ...Daha fazlası

Metaheuristics-based Pre-Design Guide for Cantilever Retaining Walls

URAY, Esra | TAN, Özcan | ÇARBAŞ, Serdar | ERKAN, İ.Hakkı

A pre-design guide for cantilever retaining walls and a detail parametric study of such walls is presented here. Mathematical models based on statistical methods were improved for calculating safety factors of sliding, overturning, and slope stability of those walls. The harmony search algorithm (HSA)-a metaheuristic method-was employed to realize reasonable results of the pre-design guide from all distinct cases. Through the design algorithm, the optimal design was determined for varied soil types differently from suggestions of design codes. Thus, an optimal pre-design guide for safe and eco ...Daha fazlası

Determining Of Safety Factors For Cantilever Retaining Wall With Mathematical Model

URAY, Esra | ÇARBAŞ, Serdar | TAN, Özcan

In the conventional design of cantilever retaining wall, trial-and-error method has been used to determine wall dimensions which satisfies the stability conditions of wall. This method takes time in design period and is not possible to know which parameter is the most effective in the design. In this study, safety factors of the cantilever retaining wall which play a crucial role in stability of the wall have been investigated to determine with mathematical model. In computing of safety factors of sliding, overturning and slope stability mathematically, Taguchi method which is a statistical me ...Daha fazlası

Investigation of Sizing Criteria for Cantilever Retaining Wall with Taguchi Optimization

TAN, Özcan | ERKAN, İbrahim Hakkı | URAY, Esra

Controllable or uncontrollable parameters like elevation difference between soil levels, soil properties, selected wall dimensions, case of groundwater, construction area, intended use and cost have been affected design of retaining walls that connects two different soil levels. In this study, factors effect on the design of the cantilever retaining walls which have an important place in geotechnical engineering applications have been investigated experimentally. For different wall height and soil properties Signal/Noise (S/N) and variance analysis have been performed separately by using L16 d ...Daha fazlası
