Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface
Deep Underground Science and Engineering, Volume 5, Issue 2, Page 350-366, June 2026.Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...
