  Assessment of a constitutive model for simulating the post-liquefaction response of sands

  , 8th International Conference on Earthquake Geotechnical Engineering

  Advanced constitutive models can be used to simulate the effects of soil liquefaction on foundations and buildings in dynamic Finite Element analyses. While various constitutive models have been applied in numerical studies considering one-time cyclic loading, there remains a need to investigate their performance for repeated cyclic loading events. Deposits in seismic areas are likely to be subjected to multiple consecutive earthquakes and aftershocks. However, the impact of the previous shaking history on the cyclic resistance of the soil and its post-liquefaction static response is the subject of ongoing research and is not yet fully understood. Based on findings from experimental studies, this paper presents an assessment of a constitutive model and its ability to capture the effects of the loading history on the sand response. This involves the simulation of laboratory element tests for different cyclic loading, reconsolidation and monotonic shearing series. A particular focus lies on model features incorporated to simulate cyclic mobility at low effective stress levels, as well as the anisotropic post-liquefaction response of the material.

  Seismic response of offshore foundations with emphasis in liquefiable ground conditions

  , 8th International Conference on Earthquake Geotechnical Engineering

  Following the rapid expansion of offshore wind farms in seismic areas, this study examines the hurdles encountered when applying conventional seismic evaluation methods, originally devised for onshore structures, to offshore installations. This includes the assessment of liquefaction offshore at large depths and its consequences on the response of offshore wind turbines supported by monopile foundations. With the aid of 3D dynamic finite element analysis of the entire SSI system (tower, monopile foundation and soil domain), it is shown that the resonant frequencies of the examined 5MW turbine were excited for the considered ground motion, inducing significant nonlinearity in the soil surrounding the monopile foundation. The vertical seismic motion, often overlooked in seismic design, is also discussed as it bears significance for the response of offshore wind turbines. Simple site response analysis for vertical ground motion emphasizes the need to consider the entire water column and soil profile depth to the bedrock for an accurate representation of the soil-water system's compression natural frequency in offshore environments.

  Engineering soil barriers to minimise annual shrinkage/swelling in plastic clays

  , Geomechanics for Energy and the Environment, Vol: 38, ISSN: 2352-3808

  Engineered soil barriers have been proposed to prevent rainwater infiltration into the underlying soil, thus improving stability of sloping ground. The use of engineered barriers on flat ground as means of preventing flooding has also been explored. This paper aims to provide proof-of-concept as to the potential efficiency of engineered barriers in minimising soil shrinkage and swelling arising from seasonal variations of water content and pore water pressures within the ground due to its interaction with the atmosphere. A series of 2-dimensional, hydro-mechanically coupled finite element analyses were conducted to this effect. Emphasis was placed on accurately modelling the stiffness of the underlying soil, accounting for its small-strain behaviour, as well as the hydraulic behaviour of all the layers involved. The results confirm that it is possible to engineer barriers to minimise shrinkage/swelling in greenfield, as well as urban, conditions and highlight the influence of barrier geometry and configuration, so that recommendations for the design of such barriers can be made.

  Effect of pile spacing on the thermal performance of thermo-active pile groups

  , Symposium on Energy Geotechnics 2023, Publisher: TU Delft OPEN Publishing, Pages: 1-2

  Thermo-active piles differ from conventional piles in a way that they have pipes embedded within them, which allow a carrier fluid to circulate through and exchange heat with the ground, in order to provide low carbon heating and cooling. Sustainability targets, such as the Merton Rule, which requires a proportion of the energy demand of the building to be generated on site using renewable sources [1, 2], have facilitated the growing popularity of designing piles to be thermo-active in the United Kingdom [3, 4, 5]. In order to fulfil these sustainability targets and to determine accurately the energy savings by designing piles to be thermo-active, the thermal performance of thermo-active piles has to be determined.

  Dynamic response of offshore foundations – from pile installation to seismic performance

  , SECED 2023: Earthquake Engineering & Dynamics for a Sustainable Future, Publisher: Society for Earthquake and Civil Engineering Dynamics, Pages: 1-12

  Dynamic analysis has an important role to play in the rapid expansion of offshore windinstallations worldwide, as it affects multiple design stages. This paper highlights the use ofdynamic analysis in two distinct aspects of offshore geotechnics. It first gives examples fromrecent Joint Industry Projects where consistent procedures for wave propagation analysis basedon impact pile driving and restrike data were established, ultimately resulting in the developmentof more reliable tools for the assessment of axial capacity of piles supporting jacket structures.Following the rapid expansion of offshore wind farms in seismic areas, the second part of thepaper discusses some of the challenges in transferring some of the existing seismic assessmentprocedures, which were established for conventional onshore structures, to offshore structures.This includes the assessment of liquefaction offshore at large depths and its consequences onthe response of offshore wind turbines supported by monopile foundations.
