Practical Risk Assessment of Ground Vibrations Resulting from Blasting, Using Gene Expression Programming and Monte Carlo Simulation Techniques

Applied Sciences, 2020
Peak particle velocity (PPV) is a critical parameter for the evaluation of the impact of blasting operations on nearby structures and buildings. Accurate estimation of the amount of PPV resulting from a blasting operation and its comparison with the ...

The database management of piling induced ground vibrations [PDF]

, 1990
The storing of ground vibration signals produced by pile driving have been stored in a database on a Nimbus personnel computer. The signals were recorded on a purpose built data logger in the form of time history traces, analysed to calculate the maximum

Mathematical prediction model for ground vibrations of nearby territories induced by high dam flood discharge

Journal of Low Frequency Noise, Vibration and Active Control
Ground vibration induced by high dam flood discharge is a relatively easily ignored but quite considerable environmental problem for the nearby territories. In this paper, Xiangjiaba hydro project was utilized as an instance to study the vibration impact

Ground-Borne Vibration Prediction in a Metro Depot Using Hybrid Train-Soil-Pile-Structure Interactions

Vibration
Train-induced ground vibrations can propagate into pile foundations, potentially causing undesirable vibration in nearby buildings, laboratories housing vibration-sensitive equipment, and manufacturing facilities for high-precision processes.

Field Measurement and Numerical Simulation of Train-Induced Vibration from a Metro Tunnel in Soft Deposits

Advances in Civil Engineering, 2021
Train-induced vibration is increasingly attracting people’s concern nowadays. In the coastal areas, many metro tunnels are built in the soft deposits, so the train-induced vibration effect is more serious.

Quantification of dynamic excitation potential of pedestrian population crossing footbridges [PDF]

, 2011
Due to their slenderness, many modern footbridges may vibrate significantly under pedestrian traffic. Consequently, the vibration serviceability of these structures under human-induced dynamic loading is becoming their governing design criterion.

Ground vibration near explosions.* [PDF]

Bulletin of the Seismological Society of America, 1949
Summary In summary, the following pulses were recognized on many or all of the records taken in the Los Alamitos region: P The first pulse to arrive. P3 A compressional pulse arriving later than P. X1, X2, X3 Three pulses assumed to be body waves traveling along deeper paths than P and P3.

Computation of ground waves from pile driving and their effects on structures [PDF]

, 2002
Present guidance on levels of vibration generated by pile driving is primarily empirical, conservative and often contradictory. The objective of this research was to model the ground waves generated by pile driving using the ABAQUS finite element program
