Nieuwstad, Bas (author)
Geothermal energy can be a great solution for the downscaling fossil fuel society, but it can potentially lead to seismic hazards. A doublet system, with a cold water injection well and a hot water production well, alters the stress situation in the subsurface, which can result in (micro)fracturing and fault reactivation. Even in water filled...

Energy piles are getting more attention for their sustainable and economic potential. The fluid pipes are integrated in the foundation piles, which makes it cost-attractive, but also relatively new to the Dutch geotechnical industry. By lowering the temperature limit of the anti-freeze fluid in the pipes the heat extraction and thereby also the...

In 2017 new guidelines concerning macro stability calculations were implemented by the Dutch Ministry of Infrastructure and Environment. These guidelines are formulated in “Wettelijk Beoordelingsinstrumentarium” (WBI). The largest difference with the previous version of the guidelines concerns the material model that is prescribed to determine...

High temperature aquifer thermal energy storage (HT-ATES) can potentially solve the mismatch between heat supply and demand. It can provide a large scale seasonal heat storage solution. Thereby it enables an increase in full load hours of the base heat source, which can benefit project performance on both costs and emissions. However, the...

In this work the installation process of a cone penetrating into a sand system is modelled using a 2D-axisymmetric material point method (MPM) model in order to investigate the installation processes and to predict the plastic radius. One meter of cone penetration is modelled under a surcharge of 50 kPa. The used constitutive model is Mohr...

The widely used cone penetration test (CPT) allows in-situ measurements of soil behaviour during continuous penetration. The traditional sensors incorporated in a cone penetrometer are for measuring cone resistance, sleeve friction, pore pressure, and inclination. Many supplementary sensors have been studied and tried in research settings and in...

In 2020 TU Delft will build a geothermal well producing enough energy to power all its faculties and a number of buildings surrounding the campus. This is done to meet the climate goals the TU set itself: an energy neutral campus by 2040. Geothermal plants are designed to produce for 30 years. After this period, by 2050, the TU has to be energy...

van Koelen, Tim (author)
The subsurface is often modelled as multiple homogeneous soil layers. In reality, the soil properties of these layers are heterogeneous and spatially variable, making it difficult to properly deduct the engineering properties that are required in the design of geotechnical structures. This leads to uncertainty in the design. The probabilistic...

High Temperature – Aquifer Thermal Energy Storage (HT-ATES) is a way to efficiently store heat with use of the subsurface. Region Holland-Rijnland has the vision to be free of the use of natural gas in 2050. A proposed high temperature heating network from the port of Rotterdam to the households of Leiden, combined with the use of an HT-ATES...

The Particle Finite Element Method is a numerical tool that has been introduced more than a decade ago for the solution of engineering problems involving large deformations. <br/>The method falls under the category of mesh-based particle methods, meaning that all information is stored on moving particles that represent the domain under analysis...

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]<br/>In order to overcome this fast increase, the human...

Constitutive models are one of the main building blocks of the Finite Element Analysis that nowadays is used in almost every geotechnical engineering project. Thus, finding realistic stress-strain behaviour models has been one of the main fields of research in Geotechnical Engineering. However, constitutive equations have become increasingly...

One of the main challenges in dike design in the Netherlands is to guarantee a sufficient safety level against the development of macro-instabilities in a dike. A case study was performed on a dike section at Herrewijnen-Opijnen, which is part of the Heesseltse Uiterwaarden in the Dutch province of Gelderland. The dike located at this site no...

In the northern part of the Netherlands, the exploitation of gas fields has been inducing small earthquakes, causing damage to existing buildings. <br/>With the aim of preventing consequences to people and structures, the VIIA Groningen project deals with CC2 and CC3 buildings retrofit and provides reinforcement measures when necessary.<br/>As...

By increase in knowledge and complexity of the projects, worldwide, more attention towards safety provision in projects is being paid. With growth in waterway traffic the need of safety provision for structures crossing navigable waters increases. Especially bridge piers and immersed tunnels on the see floor or at tunnel approaches are at bigger...

Building wind turbines near flood defences has numerous advantages over other locations on land. The water authorities, which own the land of the flood defence, will only permit the turbines if the flood protection assessment satisfies the safety standard after the wind turbines have been constructed. There are three types of failure of a wind...

One of the failure mechanisms for water retaining structures is piping. Piping is an internal erosion<br/>mechanism creating hollow spaces (pipes) underneath, for example, a dike as a result of the transport<br/>of soil particles due to seepage. The formation of pipes can cause collapse of the structure once the<br/>erosion process reaches the...

Geothermal energy is a way of reducing the cost of energy. Deep geothermal energy systems extract heat from very deep soil layers where the temperatures are very high. Shallow geothermal energy systems are about 150 metres deep and they are used to store heat in the soil, to extract it later and use it for space heating. These shallow geothermal...

Significant part of geotechnical engineering projects involve the problems related to jointed rock<br/>masses. For example, construction of tunnels in rock or stability analysis of the rock slopes. In this<br/>framework, the finite element modelling is often used for problems with complex geometries or<br/>where the analytical solution is...

Soil properties used to determine the stability of soil structures are variable in nature. Uncertainty in soil can be attributed to its inherent variability, as well as sources of error encountered while estimating the magnitude of its properties. The modelling of these uncertainties will produce more meaningful solutions when evaluating...
