Abstract

Stone column is an improvement technique to reduce total and differential settlements; accelerate consolidation; increase bearing capacity; reduce of liquefaction potential; enhance slope stability. Prediction of settlements of stone column reinforced soil is one of the most important design parameters for practical geotechnical engineers. There are many analytical, numerical and experimental studies to predict settlements in the literature. In the present study, the potential of stone columns to reduce settlement is discussed with three different analytical methods. The parameters used for these analytical methods are obtained from experimental and numerical studies that were conducted to study long term ground settlements of the stone column reinforced soil. Firstly, parametric studies were performed to investigate the effect of input parameters on the analytical methods. Later, improvement factor (ƞ) and settlement reduction factor (β) was determined based on analytical methods for design of stone column. Based on the results, analytical methods were assessed in detailed and some offers were proposed for design of stone columns.

Özet

Taş kolonlar zeminlerin toplam ve fark oturmalarının azaltılması, konsolidasyon sürecinin kısaltılması, taşıma kapasitesinin arttırılması, sıvılaşma potansiyelinin azaltılması için kullanılan bir zemin iyileştirme yöntemidir. Taş kolon ile iyileştirilen zeminde meydana gelecek oturmaların önceden tahmin edilmesi pratik geoteknik uygulamaları için önem arz eden tasarım parametrelerindedir. Oturmaların tahmin edilmesi konusunda literatürde birçok analitik, sayısal ve deneysel çalışma yer almaktadır. Bu çalışmada taş kolonların oturmaların azaltılması üzerindeki etkisi üç farklı analitik yaklaşım yardımı ile araştırılmıştır. Bu analitik yaklaşımlarda, taş kolonların zamana bağlı davranışının araştırılmasına yönelik yapılmış deneysel çalışmalar ve deneysel çalışmalara ait sayısal analizler yardımı ile elde edilen parametreler kullanılmıştır. Çalışmada öncelikle, parametrik araştırmalar yapılarak parametrelerin analitik yaklaşımlar üzerindeki etkisi değerlendirilmiştir. Sonrasında, taş kolonların ön tasarımı için iyileştirme faktörü (ƞ) ve oturma azaltma faktörü (β) değerleri analitik yaklaşımlar yardımı ile belirlenmiştir. Çalışma neticesinde analitik yöntemler detaylı olarak değerlendirilmiş ve taş kolonların ön tasarımı için öneriler yapılmıştır.
