The growth of railway ground vibration problems — A review

Science of the Total Environment, 2016
Ground-borne noise and vibration from railway lines can cause human distress/annoyance, and also negatively affect real estate property values. Therefore this paper analyses a collection of technical ground-borne noise and vibration reports, detailing commercial vibration assessments undertaken at 1604 railway track sections, in 9 countries across the ...

Free Field Ground Vibration Due to Ground Improvement Induced Vibration

2021
The present study focused on measuring free-field vibration induced by ground improvement work. Ground improvement work at the Indian Institute of Technology Patna campus was performed using the vibroflotation technique. Two different types of sensors were used to measure this ground accelerations and peak particle velocity (PPV). The minimum source to

SIMULATION OF THE GROUND VIBRATION INDUCED BY TRAIN

19th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2006
The purpose of this study is to make clear the mechanism of the ground vibration induced by trains and to develop a numerical simulation tool which can quantitatively evaluate the effect of wave filtering works. A 3D viscoelastic finite-difference method is used to study the mechanism of the ground vibration induced by train. At first, the special case

The Vibrational Ground State of 12CHD3

Journal of Molecular Spectroscopy, 1993
Abstract Within the scope of a general tensorial study of the 1000 and 2000 cm −1 polyads of CHD 3 , we have revisited the ground state of this molecule. Infrared ground state combination differences (GSCD) were calculated from 1746 transitions assigned in the ν 3 /ν 5 /ν 6 triad of CHD 3 . A set of 10 ground state parameters has been fitted to 613
