Dynamic Response and Fatigue-Life Analysis of High-Speed Railway Tunnel Base with Defects

Table 6

Comparison of fatigue life under different working conditions.

Working condition		Damage fatigue life (years)		Relative difference (%)
		Result obtained using proposed constitutive model	Result calculated by Huang [2]
Working condition 1	There is no seam in the filled layer	240	249	3.61
Working condition 2	There is a seam with groundwater in the filled layer	56	N/A	N/A
Working condition 3	There is a seam without groundwater in the filled layer	62	N/A	N/A
