Abstract

In this study, Rammed Aggregate Pier systems are analyzed according to the numerical analysis that are performed by two dimensional commercial finite element analysis software. The focus point of the paper is to identify the effects of pier dimensions, stratification of foundation soil profile and load applying levels on the deformation behavior of interacted rammed aggregate pier-surrounding soil system at the installation stage. Interpretations of the parametrical analyses are focused on the deformation change via loading levels. The relative displacement occurrence between pier and soil matrix is also checked.

Tabakalanmış zemin profillerinde inşa edilen tekil kırmataş kolonların sayısal analizi

Abstract

Bu çalışmada, Darbeli Kırmataş Kolon sistemlerinin sayısal analizi iki boyutlu ticari bir sonlu elemanlar programı kullanılarak yapılmıştır. Çalışmanın odak noktası; kazık boyutlarının, temel tabakalanma özelliklerinin ve kazık yükleme seviyesinin, inşa sırasında ve sonrasında etkileşimli kazık-semin sistemi içerisinde meydana gelen deformasyon davranışı üzerindeki etkilerinin araştırılmasıdır. Uygulanan parametrik analizlerin sonuçları düşey deformasyonların yükleme seviyesine bağlı değişimi olarak incelenmiştir. Kazık ve zemin arasında meydana gelen rölatif deplasmanlar da ayrıca kontrol edilmiştir.
