Geotextile Design & Construction Guidelines: Participant Notebook

These guidelines have been condensed from the FHWA Geotextile Engineering Manual (1985) for use as an implementationdocument for project managers and highway designers. It will also be useful as a design reference guide for pavement and geotechnical specialists. The guidelines when used in conjunction with the FHWA Geotextile Engineering Manual...

The influence of freeze-thaw cycles on the shear strength of Illite clay

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...

Physical modelling of a sheetpile-vegetation system

A study carried out to understand the effects on including vegetation as an additional reinforcement to improve streambank stability.

Suction bucket jackets for offshore wind: a reliability based analysis of geotechnical installation design

Pile Foundation and Soil Response to Deep Excavation

Construction of deep excavation in densely populated area is not a trivial thing. The execution could induce disturbance to the soil and adjacent buildings. Many researches have analysed building responses to deep excavation or tunnelling projects. But the studies were mostly limited to buildings with shallow foundations. The importance of...

On the possibility of simulating pile set-up in sand by means of centrifuge model testing

An increase over time in bearing capacity of displacement piles is often found in the field. This phenomenon is called pile set-up. The increase is predominantly caused by an increase in shaft resistance and is observed even until 1000 days after installation. In the Dutch situation, a proposed tightening of the design standard for pile...

Characterization of undrained shear strength in Dutch sites using Hierarchical Bayesian Modelling

This thesis discusses the characterization of the undrained shear strength, S_u from the net cone resistance, q_net of clay in Dutch sites using Hierarchical Bayesian Modelling (HBM). The performance of the HBM is compared with the current practice methods of the site characterization which propose either the use of only site–specific...

Geotechnical Risk Management: A Statistical Framework to Assess the Effect of Sampling Density on Dredge Performance Forecasting

This thesis proposes a methodology towards quantifying the uncertainty resulting from the density and spatial arrangement of samples and assessing their effect on forecasting key performance indicators, related to dredging and (wet) mining operations. Aside from quantifying this uncertainty, another objective of this research is to develop a...

Modelling the soil-structure interaction of 60 m long piles under gradual loading during construction of a high-rise building in Rotterdam

This thesis examines the load distribution on 60 m long piles under gradual static loading, considering the POST Rotterdam high-rise building as the study project. The research employs fibre optic (FO) instrumentation on site to monitor strain changes in the piles over time and assess load transfer mechanisms. This data is integrated into a...

Reliability analysis of the Red River dikes system in Viet Nam

This dissertation presents the applications of probabilistic-based frameworks in geotechnical and hydraulic engineering, for the assessment of the Red River dikes in Viet Nam. Dike along rivers often spread over the deltaic environment and its earthen structures are parts of a long civilian history, from hundreds to thousands of years....

Limit State Imprecise Probabilistic Analysis in Geotechnical Engineering

The treatment of imprecision attracted continuous interest since the origin of probability as the science of uncertainty. As a matter of fact, probability has been developed to deal with uncertainty and the first argument supporting precise rather than imprecise probability counts on the nature of ordinary measurements. Starting from only a few...

Limit State Imprecise Interval Analysis in Geotechnical Engineering

The first applications of nonprobabilistic interval analysis in geotechnical engineering have been recently explored. In fact, the solution of practical problems in this field often requires judgement based on limited data and interval analysis has become a research area formally motivated by input information characterised by imprecision....
