The present investigation is concerned with transient wave propagation in a rock mass set of parallel joints by using recursive method. According to the displacement field joints, interaction between four plane waves (two longitudinal-waves and two transverse-waves) joint analysed first. With discontinuity model time shifting function, equation based on method domain for obliquely longitudinal-(P) or transverse-(S) across established. are assumed linearly elastic. analytical solution...
In this study, a combination of acoustic emission (AE) method (AEM) and wave transmission (WTM) is used to investigate the behaviors AE ultrasonic properties corresponding initial fracturing in granitic rocks. The relationships characteristics, frequency spectra, spatial locations with crack initiation (CI) are studied. anisotropic velocity distributions different ray paths, amplitudes, spectral characters transmitted waves investigated. To identify CI stress, damage initiations...
Rock damage and vibration attenuation are the basis of blasting design, which will affect rock breaking results safety structures (buildings). In this paper, effect blast-hole arrangement, delay time, decoupling charge on in multihole were numerically investigated. Through dynamic analysis software ANSYS/LS-DYNA, JOHNSON_HOLMQUIST_CONCRETE (JHC) model fluid-solid coupling method used to establish single-hole models. Based vibration, firstly, above three factors characteristics was analyzed....
The topography and the incident angle of seismic waves both have considerable effects on ground motions canyons in a half-space. In this paper, theory wavefield decomposition artificial boundary is used to develop method for inputting obliquely SV waves. Formulas equivalent nodal forces applied truncated are derived implemented finite element method. validity proposed verified by test case. A parametric study then performed investigate influence canyon geometry response trapezoidal canyons....
