Application of the Heat Flow Cone Penetration Test to measure the thermal conductivity of offshore soils

Interpretation of the thermal properties of soils is an important challenge in the field of geo-engineering, for example the development of geothermal energy solutions and for the design of electricity cable routes used for offshore wind farms. Of the thermal properties, the thermal conductivity is of most interest to find, as this determines...

Benefit of starting early: Impact of monitoring and soil investigation during different project phases of dike reinforcement.

To fulfil the new safety standards of the Netherlands against flooding in the future, a great deal of work needs to be performed to prepare the flood defences system, at a quicker pace than is currently achieved. For this reason the HWBP is researching methods which can improve the efficiency of dike reinforcement projects. This thesis was...

Reducing Risk on Unexploded Ordnance by Vibrations in the Rotterdam Subsoil

During World War II the city of Rotterdam endured hundreds of air raids. Expectations are that a few dozens of UXOs are still to be found in the Rotterdam soil. UXOs can still go off to this day due to vibrations caused by construction activities. The vibration impact on the environment around the activities can be accurately predicted. The...

DelftCluster Railway transition zones & Switches: Factual report long-term measurements

For the Delft Cluster project “Railway Transition zones” extensive field-testing has been performed. Testing took place on the railway track Gouda-Goverwelle (GoGo) on a culvert and on a Switch. Many different parties were involved in the testing and numerous different types of tests were performed. Al the different tests ad up to a large amount...
