Experimental Study on the Measurement of Water Bottom Vibration Induced ...

Blasting vibration is one of the hazards induced by underwater blasting project. The characteristics of underwater blasting and the propagation laws of induced vibration are both different from those of land blasting due to the influence of underwater environments such as water mass, watersaturated sediments, and rock mass [ 1, 2 ].

Vibrational Stability of Glc/Nlc Linear Collider: Status and RD Plans*

Among the possible vibration sources in the utility tunnel are the klystron modulators and the equipment which provides cooling water. Figure 3: Vibration measured directly on the modulator (top plot), and on the floor near the modulator (bottom). The 60 Hz harmonics are removed for clarity. Vibration produced by the modulator has been studied

Evaluation and prediction of blastinduced ground vibration at Shur ...

The purpose of this article is to evaluate and predict blastinduced ground vibration at Shur River Dam in Iran using different empirical vibration predictors and artificial neural network (ANN) model. Ground vibration is a seismic wave that spreads out from the blasthole when explosive charge is detonated in a confined manner. Ground vibrations were recorded and monitored in and around the ...

Blasting vibration limits for quarries and civil construction projects

The method for measuring ground vibration is dependent on the blasting application and the type of data that needs to be collected. Velocity is the most common method used to measure ground vibration. This is because it is relatively easy to measure and it is referenced in most relevant legislation and standards.

A method for evaluating the comfort during blasting vibration based on ...

Blasting vibration (BV) has a characteristic of high frequency and short duration. Studies have shown that human beings are highly sensitive to the vibrations caused by ground and air disturbances during blasts, and their sensitivity level is approximately ten times of that of buildings (structures) ( Lucca et al., 2003; Zhang et al., 2003 ).
