Investigation of Design Criteria for the Type of Gabion Walls

URAY, Esra | TAN, Özcan

In civil engineering, connecting two different levels each other to provide the essential safety is a common problem and in solving this problem retaining structures are widely used. In this study, the design criteria of gabion retaining wall which is a kind of retaining wall was investigated by using Taguchi Method. Parameters which affect the design of gabion retaining wall are height, length of base, wall angle and angle of internal friction and slope of backfill and 16 different Taguchi design tables were formed by these using parameters. These design tables were modelled by using computer ...Daha fazlası

Gabion Structures and Design Criteria

URAY, Esra | TAN, Özcan | URAY, Kemal

Nowadays, railway is a kind of transportation due to cheap and safe. In railway construction route, many problems like supporting of lateral soil pressure, slope stability and rock fall have been experienced. Gabion basket and mesh wire have been used commonly for solution of these problems. The gabion basket is a rectangular basket which is obtained from hexagonal-double twisted galvanized mesh wire and is filled with small rock particles or stone. Gabion structures have been constructed with placing these baskets in a certain order. In railway construction, the gabion structures have been us ...Daha fazlası

Optimization of Inclined Base Cantilever Retaining Walls with The Harmony Search Algorithm

URAY, Esra | TAN, Özcan

Cantilever retaining walls have been commonly utilized to ensure stability of two different soil levels in geotechnical engineering. In design of cantilever retaining wall, there have been many soil parameters and wall dimensions affecting stability of retaining wall like angle of internal friction, cohesion, wall height, length of base, thickness of base and so on. By using traditional methods, making safety and economic cantilever retaining wall design as soon as possible is time-consuming and trying. Because of these reasons, some effective and easy to apply optimization methods have come i ...Daha fazlası

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
