Limit Support Pressure and Critical Cover-to-Diameter Ratio of Shallow-Buried Tunnel Faces in Sand-over- Clay Composite Ground

This study combines centrifuge model tests, PIV analysis, and 3D lower-bound finite-element limit analysis to reveal that the stability and failure mechanisms of shallow-buried tunnel faces in sand-over-clay composite ground are significantly governed by the soil-layer interface position and the internal friction angle of the upper sand layer, ultimately establishing a linear relationship between the critical cover-to-diameter ratio and the friction angle to guide support pressure design.
