Concrete Vibration and Consolidation
Concrete Vibration can take some time ans sometimes it just seems to take longer than it should to pour and consolidate a precast product, such as concrete pipe or a manhole section. Frustrated by sluggish procedures, The Cretex Companies’ Rapid City, South Dakota, plant determined to improve on the half hour it took to pour zeroslump concrete, consolidate it, and get the top ring in place on t...
متن کاملVibration from freight trains fragments sleep: A polysomnographic study
As the number of freight trains on railway networks increases, so does the potential for vibration exposure in dwellings nearby to freight railway lines. Nocturnal trains in particular are of particular importance since night-time exposure may interfere with sleep. The present work investigates the impact of vibration and noise from night-time freight trains on human sleep. In an experimental p...
متن کاملAssessment of Track-ground Coupled Vibration Induced by High-speed Trains
As high-speed trains operate in more and more countries and their maximum speed increases, the vibration induced by the train has become an important issue. The dynamic coupling between the vehicle, track and ground has to be assessed for its effects on safety, stability and maintenance costs. A particular issue, especially for soft soils, is the critical speed at which the train reaches the wa...
متن کاملIsolation of Performance Halls from Ground Vibration
One of the inherent characteristics of transportation systems, especially steel wheel and rail systems, is that vehicles running on the roadway or trackway generate vibration which transmits through the ground into nearby buildings. As our urban areas build up or are redeveloped, it is frequently desired for a variety of reasons to place a concert hall or theater in a location which is in close...
متن کاملVibration Generated by Underground Railway Trains
The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...
