Influence of Geological Conditions on Measured TBM Vibration Frequency
This paper examines TBM vibration as a source of information about geological conditions. An EPB TBM was outfitted with accelerometers to monitor vibration during excavation of the University Link light rail tunnel project (U230) in Seattle Washington. Impact-response testing of the TBM indicated that significant signal over a wide range of frequencies transfers from the cutterhead where vibrat...

متن کاملNumerical analysis of energy transmission through discontinuities and fillings in Kangir Dam
A considerable amount of energy is released in the form of shock wave from explosive charge detonation. Shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. The rest of the shock wave energy is transferred to rock mass as ground vibration. Ground vibration is conveyed to the adjacent structures by body and surface waves. Geological structures li...
متن کاملDesign Spectrum for Near Fault Ground Motions Considering Frequency-Dependence of CH/SC Material Behavior Regarding Laboratory and Field Shear Wave Velocity (Vs)
Introduction One-dimensional site response analysis is widely performed to account for local site effects during an earthquake. Most of these approaches assume that dynamic soil properties are frequency independent. Laboratory test results as well as in-situ testing show that shear modulus and damping ratio are dependent on the frequency of loading. Although the amplification factor at ground ...
