These primary influence factors include vibration source, ground vibration attenuation, and vibration receiver.
Councillors will not allow work to commence until they have received assurances about independent monitoring of vibration and ground movement, and may ask Williams for a bond to be forfeited if conditions are breached or damage occurs.
This paper presents a new bracing system with variable stiffness springs; this adaptive structural control system is designed to protect buildings against severe vibration and ground movement.
These two notebooks passed such tests as 26 drops from 36 inches, vibration in ground vehicles, water spillage on the keyboards, extreme temperature, dust and altitude resistance.
The assessment and calculation of perceptible vibration and ground-borne noise from the operation of railway tunnels are discussed.
Current blasting methods, if not properly designed and conducted, can create hazards like flyrock, toxic fumes, dust, ground vibration, and surface vibration created by air-blast.
Specifically, SM usage can eliminate the generation of flyrock, toxic fumes, dust, ground vibration, and surface vibration created by air-blast.
Finally, the simulated ground vibration was compared with the observed vibrations at the test site.
This paper reports the experiments carried out in five horizontal tunnels for monitoring near-field ground vibration using accelerometer-based-seismograph planted in roof/sidewalls to establish ground vibration predictors.
"I don't know how much [is] air blast and how much of it is ground vibration," he said.
