Şev Stabilitesi Kazıklarına Etkiyen Yatay Yüklerin Belirlenmesi

Şevlerin kazıklı sistemler kullanılarak güçlendirilmesi, şevlerde oluşabilecek hareketleri önlemek için kullanılan en uygun yöntemlerden birisidir.Kazıklara etki eden yüklerin tahmini,şev stabilitesi kazıklarının doğru dizaynı için önemlidir.Bu yüklerin tahminine yönelik literatürde birçok yöntemler bulunmasına karşın, bu yöntemler kullanılarak hesaplanan yükler kazık zemin etkileşimi ve yükleme koşullarına bağlı olarak farklılıklar gösterebilmektedir. Bu analitik yöntemlerin güvenilirliklerden emin olmak için kapsamlı deneysel çalışmalara ihtiyaç vardır. Bu çalışmada, esnek kazıklara etki eden yüklerin belirlenmesi için tasarlanan deneysel çalışmanın simulasyonu iki boyutlu sonlu elemanlar yöntemi ile gerçekleştirilmiştir. Merkezden merkeze kazık mesafesinin yük aktarma davranışına etkisini belirlemek amacıyla parametrik çalışma gerçekleştirilmiştir. Elde edilen sonlu elemanlar sonuçları ile ilişkili olarak esnek kazıklara etki eden yükler belirlenmiştir.

Anahtar Kelimeler:

Yanal zemin hareketi, Şev stabilitesi kazıkları, 2 Boyutlu sonlu eleman analizleri, Kazık mesafesi, Zemin-kazık etkileşimi.

Determination of Lateral Loads on Slope Stabilizing Piles

Slope reinforcement using piled structures is one of the most appropriate methods for preventing slope movements. 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 piles predicted using these methods may differ depending on soil-pile interaction and loading conditions. Comprehensive experimental works are needed in order to ensure the reliability of these analytical methods. In this study, the simulations of designed experiment for determining the load acting on the flexible piles were performed via two dimensional finite element methods. The parametric study was carried out to determine the effects of the center to center pile spacing on the load transfer behavior. Corresponding to the numerical results, the load acting on the flexible piles was investigated.
