Soga Research Group (SRG) collaborated with Lawrence Berkeley National Laboratory (LBNL) to host the second workshop of the GOES project at the Berkeley campus from September 25 to 27, 2023. Participating research teams from various countries presented updates on a range of topics, such as the full-physics modeling framework, city-scale geothermal modeling, underground coupling, and the Platform-Based Design (PBD) framework. Notably, SRG showcased its ongoing… Read More »Geothermal-based Optimized Energy System (GOES) Workshop

In Framingham, MA, a pioneering “Networked Geothermal” project is underway to explore the potential of shallow geothermal for district heating and cooling, aiming to lower carbon emissions. During 2022 and 2023, SRG carried out four distributed thermal response tests to evaluate the geothermal capabilities of the site. Presently, SRG is collaborating with HEET to design and install a distributed fiber optic sensing (DFOS) system in… Read More »Learning from the Ground Up (LeGUp)

During construction, continuous monitoring of underground tunnels can mitigate potential hazards and facilitate an in-depth understanding of the ground-tunnel interaction behavior. Traditional vision-based monitoring can directly capture an extensive range of motion but cannot separate the tunnel’s vibration and deformation mode. Phase-based motion magnification (PMM) is one of the techniques to magnify the motion in target frequency bands and identify system dynamics. Optical flow (OF)… Read More »Deformation Monitoring of Tunnel using Phase-based Motion Magnification and Optical Flow

The Soga Research Group/Center for Smart Infrastructure is working with Caltrans to develop a cutting-edge distributed fiber optic sensing system for monitoring ground anchors. The primary goal is to quantify the distributed soil-grout-anchor interaction and load/stain transfer mechanism in various ground conditions during construction, pull-out testing, and long-term service life. Field monitoring data combined with numerical modeling analysis will be used to improve design protocols… Read More »Monitoring ground anchors with distributed fiber optic sensing
