Embodiment Construction
[0016] Take, for example, vibratory rollers whose vibration frequency and operating amplitude can be adjusted electronically.
[0017] The vibration wave when the road roller is working is continuously transmitted into the soil and propagates to the surroundings. Due to the effect of geometric damping and viscous damping, its amplitude will attenuate with the increase of distance.
[0018] The propagation and attenuation of vibration waves are mainly related to the characteristics of the vibration source (the working amplitude and vibration frequency of the vibratory roller, etc.), the medium conditions (the vibration attenuation characteristics of the soil), and the distance from the vibration source.
[0019] The impact of construction vibration on buildings is mainly based on the maximum vibration velocity, maximum vibration acceleration, maximum amplitude, and spectral intensity as evaluation indicators. In this embodiment, the maximum vibration acceleration is used as the ...
