... changes with depth, these elastic waves are dispersive in nature, which means that they travel at a velocity that is dependent upon frequency (or wavelength). CSWS is a particularly attractive method of investigation for landfill engineering due to the non-intrusive nature of the method that eliminates...

The resultant parameters are the penetration rate, the torque and the reflected energy from the rock through the drilling pipes...

... great value. Next, frequency characteristics of the response acceleration records were studied. The Fourier spectra and time histories of the predominant frequency of horizontal ground acceleration in liquefied and non-liquefied areas were calculated. Then the average predominant frequency of the strong...

.... The SASW method is based on analysis of the dispersion characteristic of Rayleigh waves (R-waves) in a nonhomogeneous medium. Dispersion means that the velocity of R-waves is dependent on the frequency or wavelength, therefore, waves of different frequencies or wavelengths will propagate with different...

.... Resonance of the structure to seismic load can be avoided by maintaining a high natural frequency of the structure with a high prestress. A measures to maintain a sufficiently high prestress during strong shaking is presented. INTRODUCTION Geotextile-reinforced soil (GRS) structures have a reputation...
