Rheological characterization and microstructural features of a novel polymer-modified bentonite slurry for underground construction

During underground construction, complex conditions often degraded slurry rheological performance and compromised stability. A polymer-modified bentonite slurry was developed in this study using a novel composite polymer additive prepared by combining polyethylene oxide (PEO) and...

Failure wear mechanism and blade width effect of TBM center cutter rotation in water-bearing weakly cemented sandstone

Weakly cemented sandstone (WCS) in western China is rich in clay minerals. Water‑induced softening tends to induce rotation failure of TBM central hobs, which further causes eccentric tip damage and edge chipping and remarkably reduces tunnelling efficiency. Aiming at the poorly...
