To combat global warming a transition towards renewable energy sources (RES) is essential. Although RES have much lower life-cycle emissions, they do not offer a continuous and fully predictable output like their fossil-fuelled counterparts. Energy storage is paramount in order to include the growing share of these intermittent sources into the...

In the Westerwald area clay quarries are in production. In order to assess the stability of the slopes the geotechnical characterisation of these quarries needs to be improved. This report provides the justification for a working plan for a thorough but quick assessment of existing slopes in clay mines. Literature is consulted for the...

OPERA-PU-TUD321b<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

Cation exchange is an interfacial process during which cations on a clay surface are replaced by other cations. This study investigates the effect of oil type and composition on cation exchange on rock surfaces, relevant for a variety of oil-recovery processes. We perform experiments in which brine with a different composition than that of the...

This thesis entitled "Modelling of cyclic degradation - Development of a cyclic accumulation model and the application to a gravity based foundation" presents a new soil model to analyse the behaviour of undrained soils subjected to cyclic loading. Cyclic loading on offshore support structures for wind-turbines results in complex design...

The significant growth in offshore wind activities in boulder clay areas requires suitable cable protection solutions. It is desirable to create a trench prior installation of the cable in order to guarantee the target depth of burial. Modern equipment of available on the market can be refined in order to create a reduced footprint, both...

Presented here is the numerical investigation on seismic soil-structure interaction applying features of a rather non-conventional earthquake design. The examination focuses on the Groningen site conditions which lately experienced an induced-type of earthquake. A unique situation calls for a suitable seismic design for both existing and new...

Disposal of spent nuclear fuel and long lived radioactive waste in deep clay geological formations is one of the promising options worldwide. In this concept of the geological disposal system, the Boom Clay is considered as a potential host rock when designing a generic waste repository in the Netherlands. For design and evaluation of a...

Thermo-active structures, such as energy piles, are used to store and extract heat energy from soil. In areas with seasonal freezing and thawing, such infrastructure is subjected to changes in the soil structure and, consequently, the soil strength. This research investigated the influence of repeated freeze-thaw (FT) cycles and different...

To protect pipelines in Arctic regions they are often buried in trenches, effectively preventing damage by ice gouging. When trenching is performed in Arctic soil, subsea permafrost may be encountered at water depths up to 100 m, mainlywhile excavating clay soil. Frozen clay is an anisotropic inhomogeneous material with a tensile strength and...

In the Bloemendalerpolder two test embankments were constructed in 2010 to study the long term behaviour of embankments on very soft soils with respect to settlement and lateral pile loading resulting from horizontal soil deformations. A detailed description of the test embankments, performed soil investigation, laboratory tests and...

When it comes to flood protection, the established method is to use impermeable material in dikes, to prevent seepage. This material is usually some kind of clay soil which is considered as impermeable and erosion-resistant. Dispite that, in many occasions not only seepage, but the failure of the dam occured due to surface erosion, because these...

Excessive differential settlement along bridge approach is commonly found in the lower central region of Thailand. To overcome the differential settlement problem, engineers have developed different types of bridge approach structure and improved design procedures. Two types of bridge approach structure are currently used in Thailand, including...

Clay particles, known for their adhesive properties, are commonly encountered in underwater soils. When producing large quantities of sand by means of dredging, fines are a byproduct and cause important viscosity changing effects altering the sand settling behavior. Much is already known in this field but knowledge lacks in the area where sand...

The presence of micropollutants, especially pharmaceuticals, in wastewater has become a significant concern to both the water treatment industry as well as consumers. A new method of treatment was developed to curb this problem. The use of polymers as flocculants and combining them with materials helped to reduce the concentration of these...
