A convenient tool for geotechnical engineers to quickly determine the impact of a vibration source on the surrounding structures.
Classify CPTs using the CEMS Machine Learning model and automatically calculate the impact force of a (sheet)pile based on a chosen drive strategy.
The normative impact force for the analysed CPTs can easily be determined with a clear overview. The impact of the vibration source is clearly validated, with an overview of the affected buildings, as well as the range and extent.
Calculation data is used to create visualizations of impact force and affected buildings on the surrounding area on a map, from which downloadable reports can be generated.
The VibraCore application is used for vibration predictions and validations. In other words: Predicting or validating the impact of the drive force of a (sheet)pile installation on the surrounding structures based on Dutch regulations. For example, to calculate whether it is safe to drive a (sheet)pile at a certain location and what its' impact is on the surrounding area, more specifically the buildings.
Normally, analysing soil profiles, calculating the impact force and validating building structures requires a lot of time and different expertises. With VibraCore, you can easily insert all input parameters yourself and let the application do the calculations for you, saving you both a lot of time and money.
Calculations are based on several input variables, such as soil profile (GEF) analyses, which you can easily be uploaded and viewed within the application. The application allows you to determine a region for which the impact is calculated, for example a circle with a diameter of 150 meters. The impact force within this region depends on the location, soil structure, maximum impact force (CUR 166), and pile type that is used.
The results of the calculations are viewable on the map, with region, location of the pile(s), and buildings within the chosen region visualized. Data for the location of these buildings is all stored in a database. Within the application, you are able to delete or insert buildings manually in case this is necessary and assign them characteristics, such as floor material, to narrow down the impact force. Within the red section, you see all buildings that exceed the acceptable risk (as determined by SBR A standards). Different coloured sections specify the properties of those buildings in that region. The circles show the boundary where the specific building could be at risk of damage. The risk can be mitigated by reinforcing the building, or damping the impact force blow.
With just the push of a button, you can generate and download reports of the calculations and addresses of buildings within the region that are affected by the vibration source, so you can inform the correct people and take the correct measures where needed.
