Abstract During shield tunneling in highly abrasive formations such as sand–pebble strata, nonuniform wear of shield cutters is inevitable due to the different cutting distances. Frequent downtimes and cutter replacements have become major obstacle

Abstract In cold regions, the environment dynamics lead to variations of soil temperature, water content, and deformation, which are characterized by highly coupled physical interplay. The hydraulic and thermal properties of unsaturated soils are hig

Abstract The spewing of a screw conveyor easily occurs from the earth pressure balance (called EPB) shield in a water‐rich sand stratum. This may lead to the collapse of the tunnel face and even serious subsidence of the ground surface. To understa
