I'm thrilled to announce that our recent paper, titled "Micro-Macro Assessment of The Pile Bearing Capacity Interaction with Single and Double Voids in Different Soil Densities Using The Discrete Element Method," has been published in ASCE Publishing prestigious International Journal of Geomechanics. In this study, our team explored the impact of soil variability, influenced by environmental changes, on geotechnical considerations. We focused on underground voids, which significantly affect subsoil structures such as piles. Using a two-dimensional Discrete Elements Method (DEM) model, we investigated voids in sandy soil and their effects on pile behavior, particularly bearing capacity and lateral pressure coefficients. Our results reveal that voids can reduce pile bearing capacity by up to 63% in critical zones, mainly due to decreased resistance at the pile's tip. This highlights the crucial importance of understanding void effects for safe subsoil structure design in geotechnical engineering. I would like to express my deep gratitude to the team members, Prof. Alireza Saeedi Azizkandi and Saman Ghaderi, for their exceptional efforts, contributions, and collaboration.

Synopsis: It is very evident today that geotechnical engineering is faced with a range of challenges of increasing complexity and scope. Efforts have been made in industry and in academia to address some of these challenges, contributing to the development of a current and future safe, sustainable and resilient society. This Rankine Lecture focusses on the development of robust predictive tools to underpin the geotechnical design concerned with the lifecycle assessment of a range of infrastructure, illustrated by specific examples from the Speaker’s research. The key for these developments is in integrating, in a consistent manner, ground characterisation with rigorous computational analysis and validation through field monitoring.

#Callforpaper The Journal of Marine Science and Engineering is pleased to announce a Special Issue entitled "Advances in Marine Geotechnical Engineering—2nd Edition", which is based on the great success of our previous Special Issue with the same title. This Special Issue aims to advance different state-of-the-art survey methods in marine geotechnical engineering, marine material property determination and site investigation, constitutive models of marine geotechnical materials, and marine structural response analysis through experiments, numerical simulations, and field seafloor scour. Advances in marine geotechnical engineering can be achieved via the application of scientific knowledge and engineering techniques to the investigation of seafloor materials and the characterization of the seafloor’s physical properties. Seafloor soil behavior in relation to infrastructural construction on the seafloor is poorly understood. With the rapid development of marine resource exploration in recent years, coastal geohazard and offshore geotechnical engineering have attracted the attention of coastal geotechnical engineers and made significant progress. Authors are encouraged to submit theoretical, numerical, experimental, and applied articles addressing this theme. Guest Editor: Dr. Hem B.

This Wednesday, Min Hou, E.I.T., MSc Student in the Faculty of Engineering, University of Alberta, will present "A Numerical Investigation of Transitional Behavior in Intermediate Soils" as part of our Centre's Graduate Seminars Series! Register for the seminar at https://lnkd.in/gDGtA6sv Abstract: Failures of tailings dams and natural slopes have the potential to result in detrimental human fatalities and economic and environmental consequences, which could be attributed to a lack of knowledge of the transitional behavior in certain geomaterials. In contrast to the conventional critical state soil mechanics (CSSM), soils demonstrating transitional behavior exhibit a non-unique normal compression line (NCL) or critical state line (CSL) even at significant strains, and the mechanical response is state-dependent. This type of special soil is termed intermediate or transitional soil. The prevalence of intermediate soils in natural or engineered earthworks adds more uncertainties, particularly under high-stress conditions, and hence challenges the traditional geotechnical design. This study developed a set of discrete element models to replicate a 1D compression test on loess, particularly focusing on the transitional mechanism under extremely high-stress conditions (58,000 kPa) for the first time. The parametric investigation shows that the microscopic factors influencing transitional behavior are sample initial void ratio, average particle size, contact model type (linear or hertz), particle size distribution (PSD), and friction coefficient. In the end, two innovative indices, normalized bandwidth and ∆e ratio, are proposed to quantify the magnitude of transitional behavior and characterize soil type by linking the microscopic friction coefficient and macroscopic constant volume friction angle.   Bio: Min Hou is an MSc student in Geotechnical Engineering at the University of Alberta, supervised by Drs.

FUN FACTS ABOUT GEOTECHNICAL ENGINEERING Geotechnical engineering, despite its serious and crucial role in construction and infrastructure, has its share of intriguing and entertaining aspects. From its ancient roots to modern-day marvels, here are some fun and enlightening facts that shed light on this remarkable field: Ancient Beginnings: Geotechnical engineering has ancient origins, with evidence of early civilizations, such as the Egyptians and Mesopotamians, employing soil mechanics principles in constructing massive structures like pyramids and ziggurats. The art of foundation design goes back thousands of years! Soil Profile as a Fingerprint: Each location has a unique soil profile, like a fingerprint. Geotechnical engineers study these profiles to understand the soil's properties and behavior, crucial for safe construction. Earth's Permeability: The Earth's permeability varies widely. While dry sand can be quite permeable, clay is less so. Understanding these differences is vital in geotechnical engineering, especially in the design of foundations and drainage systems. Permafrost Engineering: In regions with permafrost, engineers use specialized techniques to build on frozen ground. These methods involve insulating foundations to prevent thawing and preserve stability.

➡️ Grateful thanks to Thomas Marcher for the opportunity to contribute as a guest #speaker at the "Advanced Rock Mechanics and Tunneling" seminar at RMT @ TU Graz. In yesterday's session, we delved into "Wide-area ground and structural #monitoring with satellite-based #InSAR," an integral component of the seminar's curriculum. This advanced technology plays a crucial role in modern engineering and environmental monitoring.   🛰️ Attendees were introduced to the practical application of InSAR data for high-precision monitoring of impacts on structures and buildings due to subsurface changes. This session emphasized the significance of accurate data in understanding and mitigating potential #risks associated with geological and environmental changes.   🏗️ Examples discussed included both natural phenomena and man-made alterations, such as groundwater fluctuations, which can have substantial effects on infrastructure. The attached image provides a clear example, showcasing the monitoring outcomes on #Vienna's city center, highlighting how these techniques are applied in real-world scenarios influenced by #construction activities. #MatchSAR #subsidence #sentinel1 #copernicus #EarthObservation #remotesensing
