Abstract (2. Language): 
In this study, in-situ proctor penetrometer and vane experiments were used to determine the pressure and shear strengths and in-situ seismic cross-hole experiments were used to determine the dynamic properties of soil. Vane and proctor penetrometer experiments were also performed where seismic cross-hole studies were carried out. Multi- parameter experimental relationships were determined from the compressive strength and shear strength which were found from proctor penetrometer and vane, and seismic velocities obtained from seismic cross-hole studies. This study suggests that the pressure and shear strengths of sand and clay predominance soils from in-situ seismic velocities can be estimated. The results show that estimation of pressure and shear strengths by using experimental relationship equations proposed is fairly at good levels.
Abstract (Original Language): 
Bu çalısmada, zeminlerin basınç ve kesme mukavemetlerini belirlemek için yerinde proctor penetrometre ile kanatlı kesme deneyi ve zeminin dinamik özelliklerini belirlemek için de sismik karsıt kuyu yöntemi kullanılmıstır. Kuyu içi sismik çalısmaların yapıldıgı yerlerde kanatlı kesme ve proctor penetrometre deneyleri de uygulanmıstır. Kanatlı kesme ve proctor penetrometre deneylerinden belirlenen kesme ve basınç mukavemeti ile karsıt kuyu tekniginden bulunan sismik hızlar arasında çok parametreli deneysel iliskiler belirlenmistir. Bu çalısma yerinde sismik hızlara baglı kum ve kil yogunluklu zeminlerin yerinde basınç ve kesme direncini tahmin etmeyi önermektedir. Sonuçlar önerilen deneysel iliskinin yerinde basınç ve kesme dirençlerini iyi derecede tahmin ettigini gösterir.
