de Jong, Lauran (author)Soil liquefaction is a phenomenon in which an otherwise stiff, loosely packed, cohesionless soil loses its strength and behaves behaves like a viscous liquid in response to a change in stress conditions. This study focuses on liquefaction under monotonic load (i.e. static liquefaction) and not cyclic liquefaction. While the role of state...master thesis 2023

Gonzalez Acosta, J.L. (author), van den Eijnden, A.P. (author), Hicks, M.A. (author)Soil liquefaction is investigated considering a saturated soil deposit and by implementing standard techniques of random field theory to distribute initial void ratio values and assess liquefaction risk. The soil domain is represented in a 2-dimensional (2D) random finite element model for the dynamic analysis of coupled behavior. Multiple...conference paper 2023

Pisano, F. (author), Betto, D. (author), Della Vecchia, G. (author), Cremonesi, M. (author)Submarine buried pipelines are often laid in trenches backfilled with loose sandy soil, which is intrinsically prone to liquefaction. When liquefaction is triggered, the soil tends to behave as a viscous fluid with vanishing shear strength and very limited ability to restrain structural displacement, for instance during the occurrence of...journal article 2022

Nokande, Saber (author), Haddad, Abdolhosein (author), Jafarian, Yaser (author)The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, in progress to propose efficient techniques for mitigating uplift. In this study, 1 g physical modeling was used to assess the performance of helical piles for decreasing liquefaction-induced...journal article 2022

Woudstra, Louis-James (author)As the construction of sub-aerial and submarine geotechnical structures increase in amount, rate and size, so do their associated risks. Often, with use constitutive models, finite element analyses (FEAs) are performed in order to identify and mitigate these risks. NorSand, which is a consti- tutive model based on critical state soil mechanics...master thesis 2021

van der Zon, Jelle (author)Tailings are the rock flour which result from the process of mineral extraction at a mine. This waste material is stored in tailings storage facilities, also known as tailings impoundments. These impoundments gradually grow in size during operation as more tailings are produced and stored over time. These structures are however also prone to...master thesis 2021

Zhang, W. (author), Askarinejad, A. (author)Submarine slope instabilities are considered one of the major threats for offshore buried pipelines. This paper presents a novel method to evaluate the ultimate pressure acting on a buried pipeline during the liquefaction of an inclined seabed. Small-scale model tests with pipes buried at three different embedment ratios have been conducted...journal article 2021

Maghsoudloo, A. (author), Askarinejad, A. (author), de Jager, R.R. (author), Molenkamp, F. (author), Hicks, M.A. (author)Planning a monitoring campaign for a natural submarine slope prone to static liquefaction is a challenging task due to the sudden nature of flow slides. Therefore, gaining a better insight by monitoring the changes in pore pressure and acceleration of the soil mass, prior to and at the onset of static liquefaction, of submerged model slopes...journal article 2021

Mohsan, M. (author), Kiyota, Takashi (author), Umar, Muhammad (author), Katagiri, Toshihiko (author)This paper investigates the settlement in a pavement due to soil liquefaction. Four 1-g shaking table tests were performed on saturated sand bed-pavement model to understand the factors affecting the liquefaction-induced settlements and their relation to the pavement thickness and width. All the tests were performed with a base acceleration...journal article 2021

Verstijnen, Bart (author)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...master thesis 2020

Zhang, W. (author)The assessment of the potentially destructive impacts of subaqueous landslides on offshore pipelines is required when the pipeline route passes through zones with a risk of mass movements. Therefore, quantifying and evaluating the ultimate load/pressure acting on the pipeline is one of the key factors in geotechnical safety design of the...doctoral thesis 2020

van Lent, E.G. (author)The stability of breakwaters in seismically active areas is not always guaranteed. A new approach to model a breakwater subjected to an earthquake is with PM4Sand. The goal of this research is to find if breakwaters subjected to earthquakes can be correctly modelled with PM4Sand.<br/>To investigate PM4Sand a breakwater subjected to an earthquake...master thesis 2020

Lamens, Pascale (author), Askarinejad, A. (author), Sluijsmans, Robbin W. (author), Feddema, Antoine (author)This paper presents an analysis of field measurements obtained during pile installation tests in a submerged sandy slope. The field test was performed in 2016 as part of the construction of a new sea lock in the Netherlands. Ground vibrations and excess pore pressures were to be limited in order to prevent damage to neighbouring locks and...journal article 2020

Lamens, P. (author), Askarinejad, A. (author)During pile installation into a submerged, sandy slope, liquefaction mechanisms including flow and cyclic liquefaction warrant attention. Because of the interconnection of these mechanisms, evaluating slope stability during and as a result of vibration-inducing construction activity is not trivial. This paper presents a practical approach to...journal article 2020

Portugal Quevedo, Hugo (author)In seismically active areas, liquefaction hazards have always been a complicated aspect to evaluate as part of the seismic design of a project. In the case of the design of critical facilities, this becomes crucial, as beyond design basis conditions may elevate the seismic loads significantly and create a considerable liquefaction risk in areas...master thesis 2019

Steijlen, Florentine (author)In this report, an experimental investigation of the influence of currents on submarine slope stability is presented for the Eastern Scheldt storm surge barrier case. Slope instabilities, including liquefaction failures, have been observed in the scour hole slopes near this barrier. The currents above the sloping bed are expected to initiate the...master thesis 2019

Wang, Frank (author)Marine pipelines are widely used for transporting hydrocarbon material. However, they can be damaged by marine geo-hazards such as seabed liquefaction, as they may sink, float or be dragged by the moving soil. One of the triggering mechanism of seabed liquefaction is the increase of seabed inclination as a result of the souring process or human...student report 2019

Tziolas, Aristotelis (author)The earthquake-induced liquefaction is a high-risk phenomenon for dredging industries, which need to set strict requirements in order to avoid potential disastrous effects for the project. Different types of liquefaction exist which can be triggered over a wide range of soil types and for different loading conditions. The liquefaction triggering...master thesis 2019
