Los sistemas socio-ecológicos evolucionan en ciclos de adaptación ecológica aumentando la resiliencia de los lugares. El objetivo de este artículo es presentar los procesos de diseño e implementación del Proyecto de Área de Actividades y Cine al Aire Libre que se aplica en uno de los valles del Campus Principal de la Universidad Mugla Sitki Koçman....

A comprehensive site investigation was carried out on the site in Kocaeli, where a transformer assembly-disassembly building was located, and it was observed that there was liquefaction risk in the area. Therefore, jet grout columns were selected as the soil improvement method. After the production of the designed jet grout columns, it was investig...

Kocaeli İli’ndeki bir trafo montaj-demontaj binasının bulunduğu arazide kapsamlı bir zemin etüdü yapılmış ve bu alanda sıvılaşma riskinin olduğu görülmüştür. Sıvılaşma riskini ortadan kaldırmak amacıyla jet grout kolonlar zemin iyileştirme yöntemi olarak seçilmiştir. Tasarımı yapılan jet grout kolonların imalatından sonra sıvılaşma riskinin ortadan...

The method of encasing the stone column with a proper type of geosynthetic material is a widely used technique to provide the required lateral confinement and to avoid the dispersion of granular column material into soft clay. Along with the improved ultimate load capacity and the reduced settlement and bulging, the geosynthetic encasement preserve...

A catastrophic landslide following a rainy season occurred in the backyard of a school building in Söke, Turkey. The landslide caused property damage and adversely affected the present forest cover. Immediately after the landslide, double-row stabilizing piles were designed and constructed based on the findings of two-dimensional (2D) finite elemen...

In this study, the effects of pile spacing and pile head fixity on the moment and lateral soil pressure distribution along slope stabilizing piles are investigated. A slice from an infinitely long row of piles with fixed pile tip in an inclined sand bed was simulated with an experimental test setup. Surficial soil displacements were monitored and r...

Load transfer to piles due to the relative movement between the piles and the moving soil is a fairly complex soil-pile interaction problem. Different analysis methods are available in literature to estimate the loads on piles. However, the predicted loads on the piles calculated by these methods vary due to insufficient representation of loading c...

In this study, the use of glass fiber reinforced plastic (GFRP) profiled passive piles in slope stability is investigated and it is aimed to contribute to the literature as the first model study regarding this topic. A special experimental setup is designed in order to model pile groups subjected to soil movement under its own weight. Soil pressure...

A key parameter in the design of a laterally loaded pile is the determination of its performance level. Performance level of a pile is usually expressed as the maximum head deflection and bending moment. In general, uncertainties in the performance of a pile originates from many factors such as inherent variability of soil properties, inadequate so...

In this study, 3D finite element analysis is carried out to investigate the behavior of single pile and a group of free-head piles subjected to lateral soil movements. The mobilization mechanism of resistance from passive pile groups is discussed from the standpoint of the arching effect. Lateral pressure distributions along piles that vary with pi...

Slope reinforcement using piled structures is one of the most appropriate methods for preventing slope move-ments. The prediction of loads acting on piles is important in order to properly design of slope stabilizing piles. Despite, different uncoupled analysis methods to estimate the loads on piles are available in literature; the loads acting on...
