BWA ARCHITECTS’ Post

Just received my first semester exam results for my M.Tech in Geotechnical Engineering at DTU, and I'm thrilled to share that I've achieved 7 CGPA. It's been a challenging yet incredibly rewarding journey, and I'm grateful for the support of my professors, classmates, and mentors. Excited to continue honing my skills and knowledge in this fascinating field! #GeotechnicalEngineering #AcademicExcellence #DTU"

We just published, in Springer, a comprehensive and an open access article on shear strength of soil- for both static to dynamic loading conditions. This article compiles state of the art information on shear strength of soil and includes results from my own research in the past 25 years as well as my award winning publications. It covers easy steps to estimate soil shear strength for different loading conditions using easily measurable index properties. This state of the art article can be used for graduate course in geotechnical engineering, specifically, advanced soil behavior. It is open access and free - a new year gift to geotechnical communities/universities who cannot afford expensive books and journal articles on shear strength of soil.

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.

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.
