The construction of No. 1 Line of Fuzhou Rail Transit crossing underneath Fuzhou Railway Station is simulated by means of MIDAS/GTS finite element software, and the rules of the shield tunneling parameters on the settlement of the existing railway subgrade are studied. The analysis shows that the settlement of the railway subgrade can be brought under effective control by prereinforcing the railway subgrade, by choosing rational excavation chamber pressure (1.2~1.5 times soil pressure) and rational grouting pressure (1.1~1.2 times soil weight stress), and by using proper shield tail grouting rate.
