Long-term health monitoring of levee cutoff wall under Garden Highway in Sacramento by distributed fiber optic sensing (DFOS) technology

USACE (US Army Corps of Engineers) is currently implementing a levee improvement project along the American River in Natomas, California. The main  measure for the levee is a Slag Cement-Cement-Bentonite (SCCB) cutoff wall with an objective to reduce potential for seepage induced distress such as backward erosion piping (BEP) and slope instability. The levee cutoff wall is constructed by a mixture of cement, bentonite and… Read More »Long-term health monitoring of levee cutoff wall under Garden Highway in Sacramento by distributed fiber optic sensing (DFOS) technology

Publication: AI on NATM Tunneling Process

Our group (Renjie Wu and Yuji Fujita) published a paper Integrating domain knowledge with deep learning models: An interpretable AI system for automatic work progress identification of NATM tunnels on Tunnelling and Underground Space Technology.  Abstract:  Finding a reliable and cost-effective approach to monitor the activities of the New Austrian Tunneling Method (NATM) tunnel construction automatically is a challenging yet important task. This study presents… Read More »Publication: AI on NATM Tunneling Process
