An application of GEOLIB: route N243

by Martina Pippi MSc on 28/06/2022

In this article I want to tell you about that time in which we could run roughly ~5000 D-SheetPiling calculations by using the Python library GEOLIB and we were able to obtain a highly optimised design.

Less piles with PileCore – Smart Grouper

by Johan Zwaan on 21/04/2022

Existing pile foundation design software does not include tools to optimize your pile foundation. Conventional software lacks the ability to deal with the variation of the subsurface, which is an important factor that influences the design and amount of construction material (piles) used. Smart grouping of CPTs can lead to a lower Xi factor and thus higher pile load capacity and an optimal design.

Implementing a vibration design method into a Python package

by Jacco Haasnoot on 05/04/2022

Leon Vrielink has written a blog about his experiences during his internship at CEMS:

From the beginning of September 2021 until February 2022, I did an internship at CEMS. During my Internship I worked on developing a python package that is able to run calculations to determine settlement that could occur when sheet piles are vibrated into the ground.

A complete vibration risk assessment in 5 simple steps, VibraCore delivers

by Robin Wimmers MSc on 04/04/2022

Installation of sheet piles in urban areas can lead to building damage. Driving of sheet piles is usually done with a vibratory hammer, which creates a vibration at the surface. This vibration travels through the subsurface to the surrounding buildings. The installation force, soil profile and building characteristics influence the intensity of the vibration and the impact on the surroundings. VibraCore uses the Dutch CUR166 for sheet piles and PrePal for foundation piles to predict the vibration velocity. Using the SBR-A the vibration limit values are set for each building and the predictions are tested. Because most attributes have a spatial component, the result is presented in maps, allowing the user to get a good overview of the spatial distribution of the risks. The VibraCore tool for calculating the impact based on sheet piles is now available in the VIKTOR platform. This blog will tell u some more about this new piece of software.

VibraCore

by Robin Wimmers MSc on 09/08/2021

In this blog post, we will introduce our most recent core: VibraCore, the tool that automates risk management of building damage during vibration work. This tool uses the cpt-model from the previous blogpost. If you haven't read it, you can find it here: Part 1 and Part 2.

Automated levee stability calculations with GeoLib

by Martina Pippi MSc on 01/07/2021

This article is written by Hassan Ali, a recently graduated student from the civil engineering program of The Hague University. The subject of his thesis regarded the automation of the current process for assessing macro stability inwards to perform calculations with a high spatial density. Hassan’s work has been supervised by the CRUX and CEMS employees Silvia Bersan and Martina Pippi.

I wrote one of the fastest DataFrame libraries

by Ritchie Vink on 28/02/2021

Ritchie Vink of CEMS makes a bold claim in his blog that he has written one of the fastest DataFrame Libraries. This achievement has been made using the Rust programming language.
