Ground vibration is the natural result of the blasting process. Many empirical formulae and methodologies including analysis of travel path effects have been developed. The scaled distance, which is the most popular approach for the calculation of the attenuation of particle velocity in the ground, has led to significant advances in the prediction of particle velocity when both explosive charge and distance vary. However, this approach does not consider the effect of ground anisotropy and existence of structural geological features on ground vibration, Therefore, in this study, the effects of these rock mass properties on types, amplitudes, and frequencies of ground vibration waves at four surface mines are examined. The results, which were implemented at Kangal coal mine, Bastas quarry and Kibris quarry, provided guidance for the extensive study at Orhaneli surface coal mine.


Effect of some rock mass properties on blasting induced ground vibration wave characteristics at Orhaneli surface coal mine
Uyar Aldaş, G. Gülsev; Bilgin, Hasan Aydın; Department of Mining Engineering (2002)
Ground vibration is the natural result of rock blasting process. In the literature, improved and empirically verified treatment of blasting induced ground vibration-structure interaction effects on both the strong motions transmitted to the structures and the structure response to these motions have been studied extensively. However, although many empirical formulas and methodologies, including analysis of travel path effects and characterization of local site effect have been developed, studying of blastin...
Propagation of transient out-of-plane shear waves in viscoelastic layered media
Abu-Alshaikh, I; Turhan, D; Mengi, Y (2001-12-01)
Propagation of two-dimensional transient out-of-plane shear waves in multilayered viscoelastic media is investigated. The multilayered medium consists of N different isotropic, homogeneous and linearly viscoelastic layers with more than one discrete relaxation time. The top surface of the layered medium is subjected to dynamic out-of-plane shear tractions; whereas, the lower surface is free or fixed. A numerical technique is employed to obtain the solution, which combines the Fourier transform with the meth...
Effect of near-fault ground motion and damper characteristics on the seismic performance of chevron braced steel frames
Dicleli, Murat (Wiley, 2007-06-01)
This study is aimed at comparing the seismic performance of steel chevron braced frames (CBFs) with and without fluid viscous dampers (FVDs) as a function of the characteristics of the near-fault (NF) ground motion and FVD parameters. For this purpose, comparative nonlinear time history (NLTH) analyses of single and multiple storey CBFs with and without FVDs are conducted using NF ground motions with various velocity pulse periods scaled to have small, moderate and large intensities. Additionally, NLTH anal...
Effect of Channel Bed Corrugations on Hydraulic Jump
Tokyay, Nuray (2005-05-15)
There have been many investigations on the effect of roughness elements on physical parameters of hydraulic jump. In practice, baffle blocks and sills are commonly being used to stabilize the location of a jump and shorten the length of a stilling basin. On the other hand, corrugations which cover the entire length of the basin may be an alternative. In the present study, hydraulic jumps on corrugated channel beds are studied experimentally. Values of 0.20 and 0.26 were used as the wave steepness of corruga...
Design and development of a modular dynamic test system for resilient mechanical components and viscoelastic materials
Bilgi, Erkin Barış; Özgen, Gökhan Osman; Department of Mechanical Engineering (2016)
Vibration is a critical phenomenon because unwanted vibration causes energy wasting, noise, premature failure etc. For this reason, control and isolation of vibration has importance. Viscoelastic materials such as plastics, rubbers etc., which show both viscous and elastic behaviors under the effect of stress, are used in many different vibration control and isolation applications. In addition to viscoelastic materials, resilient mechanical components such as springs, vibration mounts etc. are also importan...
