Abstract
Vibrations from vehicles on adjacent roads can impact sensitive instruments or structures with historic significance. The amplitudes of vibrations (A) from steady traffic in Atlanta, Georgia, were found to decay with distance (r) according to the relation Log[A(mm/s) ]=0.9-1.25Log(r(m)]. Intervening topographic relief reduces the level of vibration. Using this relation, the impact of a proposed highway was estimated to cause an 8 percent degradation in photographic images with telescope. A topographic barrier could reduce, but would not eliminate the impact of highway vibration. In a second application, a freeway access ramp was originally planned close enough for the vibrations from trucks to be occasionally felt inside the structure. In the final design, the highway was more distant and supported by pillars, reducing the vibration level to near pre-construction levels.
