Nooteboom, Tim (author)The study delves into the crucial role of undrained shear strength in the stability of civil engineering projects involving soft soils. It explores the enhancement of this strength through (pre)loading in conjunction with Prefabricated Vertical Drains (PVDs). The Stress History and Normalized Soil Engineering Properties (SHANSEP) framework is...master thesis 2023

Yost, Kaleigh M. (author), Martinelli, M. (author), Yerro, Alba (author), Green, Russell A. (author), de Lange, Dirk A. (author)Cone penetrometer tests (CPTs) are used to characterize soil for a variety of geotechnical engineering applications, including earthquake-induced liquefaction triggering assessment. Numerical modeling of CPTs is frequently used to better understand soil behavior, soil-penetrometer interaction, and engineering estimates made from CPT data....journal article 2023

Brinkgreve, R.B.J. (author), Tschuchnigg, F. (author), Laera, A. (author), Brasile, S. (author)Following up on previous research on Automated Parameter Determination (APD), in which the soil stratification and numerical model parameters are automatically derived from individual CPTs, this article describes ongoing research in which the geotechnical modelling workflow is further automated in a BIM / Digital Twin environment. Especially in...conference paper 2023

Vrielink, Leon (author)Interpretation of the thermal properties of soils is an important challenge in the field of geo-engineering, for example the development of geothermal energy solutions and for the design of electricity cable routes used for offshore wind farms. Of the thermal properties, the thermal conductivity is of most interest to find, as this determines...master thesis 2022

Zeng, Sijun (author)A random field generator based on Local Average Subdivision (LAS) method is proposed in this study in order to achieve probabilistic soil classification and quantify the uncertainty of the generated most probable geological cross section. CPT data and Robertson’s soil classification chart (1990) are adopted to classify the soil. The sole...student report 2022

Fan, Zhi Yang (author)The Port of Rotterdam (PoR) is the largest port in Europe and in order to maintain its status, it would need to expand. For the expansion, an extensive survey of the subsurface is needed for the construction of new port areas and its geotechnical structures. As part of designing the geotechnical structures, the subsurface is often modelled as...master thesis 2022

Lengkeek, H.J. (author)The Netherlands is inherently challenged by water, as a large part of the country lies below sea level and several major rivers in North-western Europe cross the country. The most prevalent form of protection from coastal and river floods in the Netherlands includes approximately 22,000 km of earthen dikes, of which 3800 km are primary flood...doctoral thesis 2022

Hehenkamp, Max (author)Risk-based and probabilistic reliability design methods are starting to be integrated into the daily geotechnical engineering practice, as shown by the current draft of EN1997 (Eurocode 7), which explicitly allows Reliability-based verification of limit states. The semi-probabilistic design methods in EN1997 are a compromise between ease of use...master thesis 2022

ter Steege, Friso (author)The Dutch pile design method, NEN9997-1, classifies screw and screw-injection piles as fully displacing. For these pile types, the design code prescribes a base factor αp 0.63 and shaft factor αs in sand of 0.009. However, an ongoing TU Delft research programme on these pile types has indicated findings conflicting with NEN9997-1. This thesis...master thesis 2022

Bierma, Sybren (author)The numerical modelling of a cone penetration test (CPT) has long been a challenging task due to the large deformations associated with the penetration of a CPT. Recent developments in advanced numerical methods have shown promising results in overcoming these difficulties by using the Material Point Method (MPM). In this thesis it is researched...master thesis 2022

Martinelli, M. (author), Galavi, Vahid (author)This paper describes an MPM formulation using linear quadrilateral elements suitable for soil-structure-interaction problems. The volumetric locking and stress-oscillations are mitigated using a reduced integration technique and the Gauss integration scheme, respectively. The formulation can be used with both structured and unstructured...journal article 2022

de Zeeuw, Guido (author)The deterministic approach for interpreting CPT soil profiles poses the serious limitation of not taking data uncertainty into account. Therefore, a Bayesian model was developed by Wang et al. (2013) that, for a given CPT profile, determines the most probable number of soil layers and most probable soil layer thicknesses by simulating and...student report 2021

Harms, Koen (author)This research looks at the workings of three design methods for piles loaded in compression and tension by modelling capacity for different soil profiles, varying parameters and load tests. Compared methods are from the NEN 9997-1 (NEN), CUR 2001-8 report (CUR) and a newly developed international standard (ISO). It is generally accepted that the...master thesis 2021

Paduli, Francisco (author)The Automated Parameter Determination project aims to provide advanced geotechnical models parameters from in-situ tests in a transparent and flexible process. The framework was initially developed for coarse-grained soils, and it was needed to be expanded to all types of common soils. This report presents the expansion of the APD database to...master thesis 2021

Schoorl, Jinse (author)Soil is an important part of a railway track structure. It provides the foundation for the structure and distributes the imposed loads. Consequently, soil has an influence on the condition of a track structure and a low quality soil can ultimately cause failure of the track structure. To be able to include the condition of a soil in the...bachelor thesis 2021

Gavin, Kenneth (author), Kovacevic, Meho Sasa (author), Igoe, David (author)Because of the deltaic nature of the Netherlands, deep soft soil deposits are widespread. Due to the population density exploitation of underground space is vital for commercial developments and transport networks. Piles are used as primary support elements in deep excavations, cut and cover tunnels, quay walls, flood defences and to provide...journal article 2021

Dick, Joost (author)This study aims for a software tool that predict secondary settlements in soft layers on which secondary dikes are founded based on cone penetration test data. In the literature study five equations have been found that relate cone resistance and friction ratio to volumetric weight and over consolidation ratio. With the volumetric weight and...bachelor thesis 2020

Gavin, Kenneth (author), Blok, S.D. (author), Eiksund, G.R. (author)Monopiles are the most commonly used foundations for offshore wind turbines (OWTs). To date these are mostly impact driven into the seabed using high-capacity hammers. The noise and vibrations caused by driving create environmental concerns and the increasing size of these foundations has resulted in alternative installation methods being...conference paper 2020

Vardon, P.J. (author), Peuchen, J. (author)Obtaining in situ thermal properties of soils is often difficult and time-consuming. Here, cone penetration test (CPT) correlations are proposed and validated for thermal properties of saturated ground, i.e. thermal conductivity and volumetric heat capacity, giving continuous profiles of the parameters, in a substantially reduced time. The...journal article 2020
