Prediction of peak particle velocity using hybrid random forest approach [PDF]

Scientific Reports
Blasting excavation is widely used in mining, tunneling and construction industries, but it leads to produce ground vibration which can seriously damage the urban communities. The peak particle velocity (PPV) is one of main indicators for determining the

Investigation of Peak Particle Velocity Variations during Impact Pile Driving Process [PDF]

Civil Engineering Infrastructures Journal, 2016
Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the

Discussion on the Discreteness of the Attenuation Parameters of the Peak Particle Velocity Induced by Blasting. [PDF]

Sensors (Basel)
The research on the attenuation law of blasting vibration has become the foundation and precondition of the effective control of blasting vibration damage. Aiming at the characteristics of low frequency, low velocity, and strong amplitude of the R wave, an improved wave component separation method based on R wave suppression is proposed.

Computation of Surface Wave Parameters and Peak Particle Velocity

Journal of Structural Technology, 2023
In recent times, the rise in terrorist activities has underscored the critical need for designing structures with blast resistance capabilities. However, many Indian codes currently in place do not adequately address the issue of blast loads. This knowledge gap poses a significant challenge to engineers who must ensure the safety and security of ...
