Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 At present, the world‐wide heavy‐haul transportation technology of cargo trains has developed rapidly. Heavy‐haul railway transportation has received extensive attention due to its large capacity, high efficiency, and low transportation costs. In order to understand the role that ferroelectric materials can play in the dynamic response of a heavy‐duty ...

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 A ballastless track is susceptible to damage and even failure of structural components under the long‐term effects of extremely high temperatures. In this paper, considering the influence of different constraint boundaries, a 1 : 4 scaled model of a ballastless track‐bridge structural system was produced and placed in a large‐sized environmental ...

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 The strength of the roadbed composed of soft rock decreases following water immersion. Cement slurry is mixed with a soft rock to strengthen the soft rock roadbed to address this problem. The uniaxial compressive strength was determined, and the triaxial compression tests were conducted to analyze muddy sandstones mixed with different amounts of the ...
