Abstract:

With field monitoring and laboratory GDS test and mercury intrusion test,a quantitative study was conducted on the microstructure of the reinforced soft clay around the tunnel near the Hailun Road Station of Shanghai Metro Line 4.The fractal dimension was calculated by the thermodynamic model,and the relationship between the fractal dimension and the vibrational load was analyzed,and the variation law of residual strain with fractal dimension was obtained.

Key words:vibrational loading; reinforced soft clay; mercury intrusion test; fractal dimension; residual strain
