Numerical Analysis of Subgrade Behavior under a Dynamic Maglev Train Load

Table 8

Comparison of technical standards for an MLS Maglev structure.

Indexes for comparison		High-speed railway design codes [39]	Zhuzhou test line	Changsha maglev express line	This study
Surface layer of subgrade bed	Thickness/m	0.4 (0.7)	—	0.3	0.3
	Filler type	Graded crushed rock	Graded crushed rock	Graded crushed rock	Graded crushed rock/group A filler
Bottom layer of subgrade bed	Thickness/m	2.3	—	—	1.2
	Filler type	Group A, B filler/improved soil	Graded crushed rock	Group A, B filler	Gravelly soil

Note. The thickness of the surface layer is 0.4 m on the track of the high-speed railway without ballasts and 0.7 m on the track of a high-speed railway with ballasts.
