INVESTIGATION OF THE RELATIONSHIP BETWEEN HYDRAULIC CONDUCTIVIY AND PHYSICAL PROPERTIES OF FINE GRAINED SOILS

Year 2018, Issue: 040, 1 - 6, 15.06.2018

Abstract

Hydraulic conductivity has been used for engineering geology related projects since last decades of

19th century in order to estimate the ability of soils to transportation of water through soil particles.

Constant and falling head test are widely used to directly measure the hydraulic conductivity values ofsoil samples based on their grain size distributions. In order to perform constant and falling head test, field investigation and undisturbed sampling works should be performed. In order to overcome the time consuming and difficult processes of field works and undisturbed sampling, numerous empirical equations have previously proposed based on physical properties of soil materials to estimate the hydraulic conductivity of soil samples. Most of these equations are based on void ratio, porosity, specific surface area, Atterberg limits and some parameters related with grain size distribution. These equations are not applicable to estimate particularly hydraulic conductivity of fine grained soils due to limitations regarding with physical properties of soil samples. In this study, in order to describe the relationship between hydraulic conductivity and physical properties of soils, tests including falling head methods and measurements of grain size distributions and Atterberg limits were performed on 15 soil samples which collected from different locations during field studies. Considering the results obtained from laboratory test, it can be concluded that there is statistically significant relationship (R2=0.94) between hydraulic conductivity and grain size index values of samples which contains gravel size materials lower than %10.

HİDROLİK İLETKENLİK İLE İNCE TANELİ ZEMİNLERİN FİZİKSEL ÖZELLİKLERİ ARASINDAKİ İLİŞKİNİN ARAŞTIRILMASI

Year 2018, Issue: 040, 1 - 6, 15.06.2018

Abstract

Hidrolik iletkenlik mühendislik jeolojisi ile ilgili projelerde suyun zemin taneleri arasındaki iletiminin

sayısal ifadesi olarak 19. yüzyılın son dönemlerinden beri kullanılmaktadır. Hidrolik iletkenliğin

doğrudan belirlenebilmesi için sabit ve düşen seviyeli permeabilite deneyleri örneklerin tane boyu

dağılımları ile uygun olacak şekilde yaygın olarak tercih edilmektedir. Sabit ve düşen seviyeli

permeabilite deneylerinin yapılabilmesi için arazi çalışmalarının gerçekleştirilmesi ve örselenmemiş

örnek alınması gerekmektedir. Örnekleme çalışmalarının zaman alıcı ve zor olması nedeniyle birçok

araştırmacı tarafından hidrolik iletkenlik değerinin zemin malzemelerinin fiziksel özelliklerinin

kullanılarak belirlenmesine yönelik olarak görgül eşitlikler önerilmiştir. Önerilen bu görgül eşitliklerin

birçoğu ise boşluk oranı, porozite, özgül yüzey, Atterberg limitleri ve tane boyu dağılım eğrisi ile

ilişkili parametreleri içermektedir. Araştırmacılar tarafından önerilen bu eşitlikler zemin

malzemelerinin fiziksel özellikleri ile ilgili sınırlamalara sahip olmasından dolayı özellikle ince taneli

zemin malzemelerinin hidrolik iletkenlik değerlerinin tahmininde kullanılamamaktadır. Bu çalışma

kapsamında hidrolik iletkenlik ile zeminlerin fiziksel özellikleri arasındaki ilişkinin ortaya

konulabilmesi için arazi çalışmaları sırasında 15 farklı lokasyondan alınan örnekler üzerinde düşen

seviyeli permeabilite deneyleri, tane boyu dağılım analizleri, Atterberg limitleri deneyleri

gerçekleştirilmiştir ve tane boyu indeksi değerleri hesaplanmıştır. Deneysel çalışmalar sonucunda elde

edilen veriler kullanılarak yapılan istatistiksel analizlerde çakıl tane boyu oranı %10’un altında olan

örneklerin hidrolik iletkenlikleri ile tane boyu indeksi değerleri arasında istatistiksel olarak anlamlı

(R2=0,94) bir ilişkinin olduğu belirlenmiştir.
