Experiments have been conducted to determine the effects of parallel and variable directional joints on ultrasonic pulse propagation in two 60 9 60 9 360 mm prismatic marble blocks containing no joints, six parallel joints, and six variable directional joints. The results indicated that the attenuation increases with increasing ratio of joints in both models, but the attenuation ratio was higher for the variable directional jointed model than for the model with parallel joints. The relationships between the number of joints and ultrasonic pulse velocities were statistically investigated and the results were evaluated with those found in literature.
