Wang, H. (author), Wang, L. Z. (author), Askarinejad, A. (author), Hong, Y. (author), He, B. (author)Piles have been widely used as foundations to resist lateral loads. For the design of a laterally loaded pile, one of the most important inputs is the ultimate soil resistance (p<sub>ult</sub> = K<sub>ult</sub>Dσv<sup>′,whereK</sup>ult is the ultimate lateral soil resistance coefficient, D is the pile diameter, and σv<sup>′</sup> is the...journal article 2023

Wang, H. (author), Lehane, B. M. (author), Bransby, M. F. (author), Askarinejad, A. (author), Wang, L. Z. (author), Hong, Y. (author)Monopiles are the most popular foundation for offshore wind turbines. These foundations typically have a low length to diameter ratio and undergo a rigid body rotation when subjected to lateral load. This paper presents results from an extensive numerical investigation involving 3D finite element analyses to demonstrate that the lateral...journal article 2022

Li, Q. (author), Gavin, Kenneth (author), Askarinejad, A. (author), Prendergast, L. J. (author)The influence of combined loading on the response of monopiles used to support offshore wind turbines (OWTs) is investigated in this paper. In current practice, resistance of monopiles to vertical and lateral loading is considered separately. As OWT size has increased, the slenderness ratio (pile length, L, normalised by diameter, D) has...journal article 2022

Duffy, K. (author), Gavin, Kenneth (author), Askarinejad, A. (author), Korff, M. (author), de Lange, D.A. (author), Roubos, A.A. (author)Large areas of the Netherlands are dominated by deep, soft soil deposits, posing a challenge to engineers with respect to the design of axially loaded foundations. The design of these foundations is primarily based on methods which use cone penetration test (CPT) parameters, such as that outlined in the Dutch national standard NEN 9997-1. A...conference paper 2022

Askarinejad, A. (author), Wang, H. (author), Chortis, Giorgos (author), Gavin, Kenneth (author)The scour protection layers are usually installed around the monopiles to prevent the formation of scour hole. While extensive studies have been performed on the effectiveness of scour protection layer as mitigation measure, no study to date has been found to quantify the influence of scour protection layer on the lateral response of...journal article 2022

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

Li, Q. (author), Askarinejad, A. (author), Gavin, Kenneth (author)The majority of offshore wind structures are supported on large-diameter, rigid monopile foundations. These piles may be subjected to scour due to the waves and currents that causes a loss of soil support and consequently decreases the pile capacity and system stiffness. The results of numerical models suggest that the shape of the scour hole...journal article 2021

Sitarenios, Panagiotis (author), Casini, Francesca (author), Askarinejad, A. (author), Springman, Sarah (author)This paper interprets the hydromechanical behaviour of a steep, forested, instrumented slope during an artificial rainfall event, which triggered a shallow slope failure 15 h after rainfall initiation. The soil's mechanical response has been simulated by coupled hydro-mechanical finite-element analyses, using a critical state constitutive...journal article 2021

Wang, H. (author), Wang, Lizhong (author), Hong, Yi (author), Askarinejad, A. (author), He, Ben (author), Pan, Hualin (author)The large-diameter monopiles are the most preferred foundation used in offshore wind farms. However, the influence of pile diameter and aspect ratio on the lateral bearing behavior of monopiles in sand with different relative densities has not been systematically studied. This study presents a series of well-calibrated finite-element (FE)...journal article 2021

Li, Q (author), Prendergast, L. J. (author), Askarinejad, A. (author), Chortis, G. (author), Gavin, Kenneth (author)The majority of offshore wind turbines are founded on large-diameter, open-ended steel monopiles. Monopiles must resist lateral loads and overturning moments because of environmental (wind and wave) actions, whereas vertical loads tend to be comparatively small. Recent developments in turbine sizes and increases in hub heights have resulted...journal article 2020

Li, Q. (author), Prendergast, Luke J. (author), Askarinejad, A. (author), Gavin, Kenneth (author)The majority of installed offshore wind turbines are supported on large-diameter, open-ended steel pile foundations, known as monopiles. These piles are subjected to vertical and lateral loads while in service. In current design practice, interaction of vertical and lateral loads are not considered, rather piles are designed to resist...review 2020

(author)Predicting the trigger of a slope failure of a steep Alpine scree slope in south-west Switzerland is challenging. The groundwater (GW) flow from snow-melting and rainfall infiltration during summer changes the susceptibility to surficial failure, which also depends on the slope angle, bedrock geometry, stratigraphy and the shear strength of the...journal article 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
