Efficiency of Nearly Periodic Structures for Mitigation of Ground Vibration

  title={Efficiency of Nearly Periodic Structures for Mitigation of Ground Vibration},
  author={Lars Vabbersgaard Andersen and Andrew Peplow and Paulius Bucinskas},
Periodic structures are known to produce passbands and stopbands for propagation of vibration energy within the frequency domain. Sources vibrating harmonically at a frequency within a passband can lead to propagation of energy through propagating modes over long distances. However, sources vibrating at a frequency within a stopband excite only nearfields in the form of attenuating and evanescent modes, and the energy decays with distance. The decay phenomena are due to destructive interference…

Pile driving and other activities in the built environment cause ground vibration at low frequencies. This may result in annoyance to people as well as damage to civil structures. It is known that



Mitigating ground vibration by periodic inclusions and surface structures

Ground vibration from traffic is a source of nuisance in urbanized areas. Trenches and wave barriers can provide mitigation of vibrations, but single barriers need to have a large depth to be

Calculation of vibration transmission over bedrock using a waveguide finite element model

A finite element method is developed for the study of elastic wave propagation in layered ground environments. The formulation is based on a spectral finite‐element approach using a mixture of

Ground vibration generated by a load moving along a railway track

The propagation of vibration generated by a harmonic or a constant load moving along a layered beam resting on the layered half-space is investigated theoretically in this paper. The solution to this

Mitigation of Traffic-Induced Ground Vibration by Inclined Wave Barriers: a Three-Dimensional Numerical Analysis

Double sheet pile walls can be used as wave barriers in order to mitigate ground vibrations from railways. The present analysis concerns the efficiency of such barriers, especially with regard to the

Impedance of Surface Footings on Layered Ground

Numerical modelling of ground vibration caused by elevated high-speed railway lines considering structure-soil-structure interaction

Construction of high-speed railway lines has been an increasing trend in recent years. Countries like Denmark and Sweden plan to expand and upgrade their railways to accommodate high-speed traffic.
