Analysis of constitutive models for peat under deviatoric loading

The comprehensive assessment of the deviatoric behaviour in peats is paramount in ensuring the resilience of soil structures. The understanding of this material is riddled with intricacies, given its highly complex fabric, which includes organic matter such as fibers. This thesis evaluates the capabilities of a recent constitutive model (JMC) to...

Long-term settlement behaviour in soft soil areas for stress levels below the yield stress

Long-term settlement is unavoidable but by good prediction accompanied risks can be reduced. Nowadays linear isotach models belong to the state of the art but result in very small strain rates when small load increments or unloading is applied. For that reason this study has focused on the validation of those predictions using InSAR. Different...

The effects of forelands on embankment breaching in coastal and river regions

Embankments are one of the key aspects of flood protection programs. As the sea levels are expected to rise the coming decades coastal protection is becoming increasingly important. To better prepare for the future, increased understanding of embankment breaching is desired. An area of embankment breaching that has been relatively left untouched...

Stability assessment of the landside slope cover on clay flood embankments in the Netherlands

Large parts of the Netherlands are vulnerable to flooding. Due to the great impact that a flood would have for the Dutch society, The flood safety standards are very strict, which means that the required failure probability of flood defences is very low. To keep the flood risk within acceptable limits of the hinterland, flood embankments are...

Experimental study on the influence of bed protections on scour depth and scour development in front of sloped embankments

On the seabed in front of coastal structures sediment movement takes place due to incoming waves. The erosion of sediments creates a scour hole at the toe of structures such as embankments, breakwaters and dikes. This scour hole may lead to instabilities in the main structure due to material sliding into this hole. A common method of protecting...

Numerical Modelling of Liquefaction Under Embankments Subjected To Cyclic Loads By Wind Turbines

Recent development have caused that the policy regarding the installation of onshore wind turbines on embankments has changed to 'Yes, provided that ...' in the Netherlands. (Simplified) approaches are available within professional practice to analyse the risk of liquefaction, but are considered to be conservative. In this thesis, a methodology...

Simulation of flooding due to embankment breaches by Delft3D Flexible Mesh: Case study of coastal area in Shanghai

As a low-lying city, Shanghai faces threats from typhoon and spring tide under the condition of climate change and land subsidence. With high water level at the toe, the sea embankment is likely to be overtopped and breached, finally resulting in inundation inland.  The objective of this research is to study climate change...

Horizontal deformation of the High Speed Rail track: A study into the horizontal deformation of a sand embankment on asymmetrical soft soil for a hight speed rail track - case study HSL Rijpwetering

The high speed rail line in the Netherlands, constructed since 2002, is built to create a fast travel connection from Amsterdam to Rotterdam and the Belgium border. The track is designed for trains with a maximum operating train speed of 300 km/h. A great part of the structure is founded on typical Dutch soft soils consisting of Holocene clay...

Contributions of a time-dependent 3D coupled analysis of a system of relief wells

The maintenance and improvement of river embankments plays a crucial role in granting the safety and ensuring the quality of life of the inhabitants of the Netherlands. While the threat posed by storm surges has been greatly reduced since the implementation of the Deltaworks, riverine areas in the west of the country are characterised by the...

Efficiency of a Column Supported Embankment in Sabkha Soil

This thesis report presents an investigation of a soil improvement technique that is being executed for a Van Oord project in Kuwait. The soil is improved by the use of a column supported embankment, consisting of sand columns installed in a soft soil layer and a sand platform. The efficiency of this method is defined in terms of stress transfer...

GEOWALL® as a Quay wall

Bank protections are currently constructed with stone, wood, concrete and steel. NETICS has introduced a sustainable and commercially very attractive alternative called the GEOWALL. The goal of this study is to find a viable field of application within the quay structures by considering the arising challenges of a larger scale wall. Additionally...

Numerical model for the induced failure of the Leendert de Boerspolder embankment

The investigation performed for this MSc graduation thesis has focused on the creation of a numerical model for the induced failure of the trial embankment in location B within the Leendert de Boerspolder. What has been modeled in this MSc graduation thesis project is a 2D cross section of the mentioned embankment. Later on its safety has been...

Arching in basal reinforced piled embankments - Validation of the concentric arches model

Infrastructural projects such as roads and railway tracks are usually built on an embankment of sand or granular material. When building on soft soils, the prevention of differential settlements and resulting damage is traditionally done by including a long consolidation period in the construction process. One method to decrease construction...

Piled embankments with geosynthetic reinforcement: Numerical analysis of scale model tests

In the last few years, the CUR committee 159B has been working on the new Dutch Design Guideline for the design of piled embankments. To validate the guideline several field tests have been performed. From the field measurements is concluded that the design method is very conservative. Improving the design guideline will reduce the construction...

Stability analysis of Embankments located within A-8 interstate motorway Wroc?aw by-pass

Roads support our daily life, and play crucial role in supporting the infrastructure for economic activities. However, road disaster can be caused by different natural conditions of slope failures such as rainfall, steep topography, brittle geology, etc. Road disaster occurrences do not only cause the primary disaster from the infrastructure...

A study of possible bank protection measures near the Meghna Bridge, Bangladesh

In 1990, in Bangladesh, the "Meghna roads and highway bridge"was finisthed. This bridge is the first one in a series of two Bridges replacing the ferries over the Upper Meghna River. During construction, and also after the finalization of the Bridge, it was revealed that the designers of this Bridge underestimated the power of the Upper Meghna...
