Water induced crack initiation in an aquifer. An elastic analytical approach

Anchor Chain Cutting Through a Rock Cover

An ever-increasing number of cables and pipelines are being laid on the bottom of lakes, channels, rivers, seas, and oceans. Various hazards threaten these pipelines and cables, which in case of occurrence can cause (severe) environmental and/or economic damage. Pipelines and cables can be protected against these attacks by dumping protective...

Verification and numerical implementation of a 3D liquefaction model

With the advancement of solution techniques and solving computers, 3D analysis of civil engineering problems has increasingly become more interesting. The multiple spring model is one of the tools to give good solutions to 3D liquefaction analyses. In this model, the deviatoric stress is determined in a finite number of springs distributed over...

Failure of Peat Dikes due to Drought

This research investigates the Wilnis dike failure that occurred in the dry summer of 2003. It is believed that drought played an important role in decreasing the stability of the dike, finally leading to failure. In the reported MSc project the situation during drought is simulated with the help of finite element method programs Plaxis and...

Process and stability of slow moving landslides

The stability of the slow moving Big Rock Mesa (BRM) landslide located in California (USA) was analysed. A detailed description of its geometry and soil structure is presented. For the stability vital shear zone and unsaturated zone were identified. The strength and permeability of the different layers that exist in the BRM were determined using...

Characterisation of Saturated Loose Sand Samples prepared by Fluidization

The following thesis has three major purposes: (1) to explore the static liquefaction phenomenon in saturated sand as a relevant geotechnical hazard, (2) to show the conventional testing procedures for index characterisation and strength testing of saturated fine sands at low stress levels, and (3) to look into the fluidization mechanism and the...
