Temporal variation laws of longitudinal stress on cross section of shield tunnels
Yantu gongcheng xuebao, 2021 The longitudinal stress acting on the cross section of shield tunnels will affect the waterproof properties of the segments and the stiffness of the circumferential joints, which will thus affect the development trend of the longitudinal nonuniform ...

Nanogranular origin of concrete creep [PDF]
Proceedings of the National Academy of Sciences, 2009 Concrete, the solid that forms at room temperature from mixing Portland cement with water, sand, and aggregates, suffers from time-dependent deformation under load. This creep occurs at a rate that deteriorates the durability and truncates the lifespan of concrete structures.
