A UC Berkeley engineering research team, led by Professor Kenichi Soga, was recently granted$3 million by the California Energy Commission to enhance the seismic risk assessment ofnatural gas storage and pipeline infrastructure. Over a 3 year period, the team will employ anovel blend of remote and embedded sensing technology alongside advanced datamanagement and analysis techniques for continuous monitoring of gas infrastructure. Thesemethods will be integrated… Read More »CEC awards $3 million to integrate advanced technologies for enhanced risk assessment

On November 17th, 2023 at the 7th Annual UC Berkeley Geotechnical Engineering Research Symposium, Jaewon presented as a Keynote Speaker on the “Monitoring Capabilities of Distributed Fiber Optic Sensing for Hydraulic Fracturing“. Opening with an overview of the distributed fiber optic sensing (DFOS) technology, Jaewon shared insights from a case study in Austin Chalk / Eagle Ford Shale, where DFOS was deployed to monitor temperature,… Read More »SRG at the 7th Annual GeoSymposium

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

The UC Berkeley team participated in a full-scale field test of grout piles using Distributed Fiber Optic Sensing (DFOS) to measure strain and temperature development throughout the project. The project involved the construction and load testing of 5 drilled grout columns for a Caltrans embankment construction project in Indianola, CA. The types of monitoring performed by the UC Berkeley team included Distributed Strain and Temperature… Read More »DFOS-embedded Drilled Column Load Testing for CALTRANS Eureka

Jaewon presented her research “Hydraulic fracture stage identification and size estimation using distributed strain and temperature sensing” at The International Meeting for Applied Geoscience & Energy conference in Houston, Texas on August 30th, 2023. In this work, Jaewon worked with our colleages at Lawrence Berkeley National Laboratory, Rice University, and SM Energy to assess the use of Brillouin-based Distributed Strain Sensing (DSS) and Raman-based Distributed… Read More »Jaewon’s Presentation at IMAGE’23 Conference

Dayu attended the ASCE Geo-Risk conference at Arlington, VA, on July 23-26, 2023. He delivered a presentation titled “Unsupervised Soil Clustering and Anomaly Detection Based on EPB TBM Data”. In this work, he used a combination of Principal Component Analysis (PCA) and Local Outlier Factor (LOF) to project TBM operation data points into an embedding space and measure the degree of anomaly. This work is… Read More »Dayu’s Presentation at ASCE Geo-Risk Conference

Professor Kenichi Soga wrote an article for the Spring Bridge on Sustainable Smart Cities. This issue examines “smart infrastructure, sustainability, net zero carbon options, and autonomous driving, among other approaches to smart and sustainable cities” in the face of “increasing threats from natural disasters, aging infrastructure, traffic, and resource constraints. Professor Soga’s article focuses on ways to rehabilitate or create the built environment so that… Read More »Kenichi’s Article for NAE Bridge Magazine Spring Issue “Sustainable Smart Cities”

We had our group dinner to say goodbye to Sumeet, who will be joining IIT Delhi as faculty later this month. Best wishes to you!
