Ground Vibration Analysis Services

Definition

Ground vibrations is a technical term that is being used to describe mostly man-made vibrations of the ground, in contrast to natural vibrations of the Earth studied by seismology.

Overview

Ground vibration monitoring is the process of measuring and recording the movements in the ground. As vibration occurs at a source, a seismic wave travels causing soil and rock particles to move back and forth over very small distances. This is known as particle velocity. The vibration monitor measures the Peak Particle Velocity: the maximum speed of a particular particle as it oscillates about a point of equilibrium, caused by the traveling seismic wave. By measuring the Peak Particle Velocity in inches per second, operators indicate whether damage is likely to occur to surrounding structures.

Ground vibration analysis records vibrations caused by traffic and construction projects as well as quarry and mining operations. Engineers and construction companies usually assess their ground vibration to make certain that machinery and construction work does not cross a threshold, causing structural damage to neighbouring buildings and infrastructure. Likewise, quarry and mine operators monitor the vibration caused by blasts, compaction methods, and heavy machinery/equipment.

The professional staff at ROKADE group has the technical expertise and state-of-the art equipment to monitor ground vibrations resulting from any source (blasting, soil compaction, demolition, pile driving, and other construction operations).

Blasting is one of the primary operations carried out during mining, quarrying and many civil engineering applications such as site levelling, foundation and trench excavations, etc. Ground vibrations are an indispensable vice of this blasting. Ground vibrations can perturb people, buildings and sensitive equipment in case of hospitals, broadcasting stations, religious institutions, heritage structures etc. At a certain magnitude, the ground vibrations can also cause significant damage to the neighbouring structures. Therefore, it is paramount to measure and control ground vibrations to safeguard the lives and property of the neighbourhood.

ROKADE RotoTechniks provides end-to-end Ground Vibration Measurement and analysis of a project. We conduct initial as well as ongoing monitoring of ground vibrations to ensure that the guidelines of mining, quarrying, and environment comply. We also provide third-party testimonials on vibrations generated in the blasting.
