A Review on Soil Reinforcement Technology by Using Natural and Synthetic Fibers

Öz

Soil reinforcement techniques are frequently used to improve the engineering properties of soils in geotechnical engineering applications. For this purpose, natural and synthetic fibers have managed to attract the attention of geotechnical engineerings as an alternative reinforcement technique to traditional stabilization methods due to their sufficient strength, low cost and easily availability. The purpose of this study is to create a review on the effects of parameters such as fiber type, physical and mechanical properties of fiber, fiber quantity, fiber length and fiber surface roughness on the engineering properties of different types of soils, according to data of scientific studies on the reinforced-soils using different types of natural and synthetic fibers. Besides, this study contains information about the effects of water in the soil matrix on the behavior of natural fibers and the recommended treatments, in addition to the mechanical behavior of the fiber-soil composite.

Zeminlerin Doğal ve Sentetik Lifler ile Güçlendirilmesi Üzerine Bir Derleme Çalışması

Öz

Geoteknik mühendisliği uygulamalarında zeminlerin mühendislik özelliklerinin geliştirilmesi amacıyla sıklıkla zemin güçlendirme teknikleri kullanılmaktadır. Bu amaç için son zamanlarda yeterli dayanımları, düşük maliyetleri ve kolay ulaşılabilirliklerinden dolayı doğal ve sentetik lifler, geleneksel stabilizasyon yöntemlerine alternatif bir güçlendirme tekniği olarak araştırmacıların dikkatini çekmeyi başarmıştır. Bu araştırmanın amacı; literatürde farklı türde doğal ve sentetik lifler ile zeminlerin güçlendirilmesi üzerine yayınlanmış bilimsel çalışmaların verilerini kullanarak lifin türü, fiziksel ve mekanik özellikleri, miktarı, uzunluğu ve yüzey pürüzlülüğü gibi paremetrelerin farklı türdeki zeminlerin mühendislik özellikleri üzerine etkileri hakkında bir derleme çalışması oluşturmaktır. Ayrıca bu çalışmada zemin ortamındaki suyun, doğal liflerin davranışı üzerine etkileri ve alınabilecek önlemler ile lif-zemin kompozitinin mekanik davranışı hakkında bilgiler verilmektedir.
