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.

We are thrilled to announce that Behnam V. Damirchi, Ph.D. from #TetraTechCoffey is one of the selected Candidates invited to present their papers at the Australian Geomechanics Society WA chapter meeting on the 9th of July. Behnam’s presentation is titled “Revisiting Hydro-Mechanical Coupling in Geotechnical Engineering: Analysing Fractured Porous Media with a Newly Developed FEM-Based Approach”. In this presentation, Behnam will delve into the complexities of the necessity of revisiting the coupled seepage-stress processes in geological porous media consisting of arbitrarily oriented fractures and discontinuities. This discussion could benefit academics, practitioners, and designers in the fields of geotechnical engineering. Behnam explains, “I bring both academic and industry perspectives to this topic and aim to combine these views to discuss a subject that is central to many failures in geomechanics and geotechnical engineering”. Thank you, Behnam for sharing your valuable knowledge to help advance geotechnical engineering!

I am pleased to share along with my co-authors PIYUSH KUMAR Aayush Yadav Pradeep Singh that our recent article has been published in the International Journal of Geomechanics, ASCE. With the increasing construction of tunnels near existing buildings, prioritizing their protection and assessing their suitability for use is crucial. Our study provides valuable insights into the practical implications of planning and constructing asymmetrical tunnels—a common scenario where new tunnels with varying shapes are built near pre-existing ones. In this research, we investigated the influence of various tunnel geometries on the behavior of a shallow foundation subjected to uniform loading positioned above a single/dual-tunnel system. The special significance of this study lies in its ability to guide the design of surrounding structures and identify specific zones around tunnels that require attention, ultimately contributing valuable insights for establishing suitable support systems. We hope our findings will contribute to safer and more efficient tunnel construction practices. #Geomechanics #TunnelConstruction #ASCE #Research #CivilEngineering https://lnkd.in/gnuzEUJc

New Publication Alert! We're excited to announce our latest publication in the International Journal of Geomechanics, ASCE: "Probabilistic Seismic Stability Analysis of Reinforced Soil Retaining Structures in Partially Saturated Conditions." In this study, we propose an alternative to traditional deterministic methods that often ignore the uncertainty associated with design parameters and assume extreme soil conditions (either fully dry or fully saturated), which don't always reflect real-world scenarios. We present a simplified yet robust probabilistic approach using the collocation-based stochastic response surface method. Our proposed method effectively considers the influence of partially saturated backfill, seismicity of the location, and uncertainties associated with the soil and environmental conditions, providing a more reliable framework for the design of reinforced soil retaining structures.

➡️ 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

#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.

Yesterday (6th February 2024), our Managing Director and Chair of the British Geotechnical Association (BGA), Andrew Ridley, delivered the closing remarks at the BGA's half-day mini-symposium on 'The Observational Method'... "Today’s symposium has outlined the principles of the Observational Method and demonstrated how it can be applied. I hope it is clear that whilst good monitoring is an essential part of the Observational Method, it is not the only part, and just because one is undertaking field monitoring doesn’t mean you are adopting OM. Contracts, cooperation, back analysis and an action plan are also vital parts of the process. Advances in technology are making it possible to undertake analysis of ground and structural behaviour in near real-time, but this means that those charged with making decisions on the basis of field measurements must have the experience to do so, and therefore the appointment of a monitoring specialist is essential. Rather like Formula 1, the opportunity exists to make rapid decisions on the basis of real measurements, to bring the car into the pits at the right time and send it out in the lead. However, there is always a potential for things to go wrong in the pits if the team has not made the proper preparations, and each role requires a trained and experienced person to ensure that the operation goes smoothly. When applied well though, the Observational Method provides an excellent opportunity for geotechnical engineers to add significant value, not only in terms of time and money, but also in terms of safety and the increasingly important carbon footprint of a project". Geotechnical Observations was a proud sponsor of this event. #geotechnics #geotechnicalengineeering #geotechnicalobservations #observationalmethod #monitoring #carbonfootprint #
