Shield Tunnel Structure Modal Analysis with Floating Slab Track on Elastic Foundation
A finite element model (FEM) was proposed to analyze the model of floating slab track (FST) system based on elastic foundation in shield tunnel, and the equivalent model of continuous girder and theory of beam on elastic foundation were considered. Floating concrete slab eigenfrequencies can be calculated under the various combinations of subgrade reaction coefficient, steel spring support stiffness, fastener stiffness and thickness of the floating slab. The results show that geological conditions had certain effects on the eigenfrequencies of FST.
