...Qingbo Bai; Xu Li; Zhenze Ma; Xiaokang Li; Long Liu Purpose Conventional high-speed railways (HSR) subgrade design methods remain constrained by platform-dependent drafting systems, leading to data interaction hindrances and redundant design processes. This study strives to develop a digital...

...Yunjia Wang; Qianli Zhang Purpose It is of great significance to study the influence of subgrade filling on permafrost temperature field in permafrost area for the smooth construction and safe operation of railway. Design/methodology/approach The paper builds up the model...

...Qinghong Fu Purpose This study aims to investigate the service performances of a new full-section asphalt concrete waterproof sealing structure (FSACWSS) for the high-speed railway subgrade through on-site tracking, monitoring and post-construction investigation. Design/methodology/approach...

...Yangsheng Ye; Degou Cai; Lin Geng; Hongye Yan; Junkai Yao; Feng Chen Purpose This study aims to propose a semiempirical and semitheoretical cyclic compaction constitutive model of coarse-grained soil filler for the high-speed railway (HSR) subgrade under cyclic load.
