Abstract

An ultrasonic sound wave has been used in rock mechanics to determine rock properties for many years, since it is a relatively simple, low-cost and non-destructive testing method compared to others. In this study, the ultrasonic sound (P and S) waves, density, weight and volume as the water absorption rate, Schmidt surface hardness index and porosity were determined both for dry and water-saturated samples regarding 11 different types of granitic rocks. The relationship between static and dynamic elastic modules and poisson ratio were investigated. Dynamic and static elasticity is determined by mathematical and experimental respectively. It is found that there is no correlation between calculated and experimental elasticity modulus for dry samples, but high correlation between saturated samples. As for the dynamic and static poisson ratio, the correlation coefficients are determined for dry and saturated samples as 0.49 and 0.25 respectively. It is determined that the usage of dynamic poisson ratio is not suitable for rocks used in the study

Özet

Kaya mekaniğinde Ultrasonik ses dalga hızları, oldukça basit, düşük maliyetli ve numuneye zarar vermeyen yöntemlerden olmasından dolayı kaya özelliklerini belirlemede uzun yıllardan beri kullanılmaktadırlar. Bu çalışmada 11 farklı türdeki granitik kayaç kuru ve suya doygun numunelerinde ultrasonik ses (P ve S) dalgaları, yoğunluk, ağırlıkça ve hacimce su emme oranı, Schmidt yüzey sertlik indeksi değerleri ile porozite değerleri belirlenmiştir. Ayrıca, numunelerin statik ve dinamik elastik modülleri ile poisson oranları arasındaki ilişkiler incelenmiştir Dinamik elastisite matematiksel, statik elastisite deneysel olarak belirlenmiştir. Hesaplanan elastisite modülü ile deneysel elastisite modülü arasında kuru numuneler için korelasyon olmadığı, ancak suya doygun numuneler için yüksek bir ilişki mevcuttur. Dinamik ve statik poisson oranı için ise, korelasyon değeri kuru numunelerde r: 0.49, suya doygun numunelerde ise r: 0.25 olarak belirlenmiştir. Çalışmada kullanılan kayaçlar için dinamik poisson oranının kullanılmasının uygun olmadığı görülmüştür
