Abstract
Considering the nonlinearity and uncertainty of first tunnel hoop stress changes that caused by the construction of underwent tunnel in Suzhou metro line 4. According to the basic principles of fractal theory, Hurst index of the hoop stress time series was calculated by using R/S and V/S analysis method. The effectiveness of both method and non-cycle of surface deformation are analyzed combined with V statistic. The results show that both R/S and V/S analysis method for the analysis of time series of hoop stress has good validity. The Hurst index gets from R/S analysis method is bigger than that of V/S analysis method. Hurst index of B section in hoop stress time series approaches to one, which suggest that change rule with a strong regularity. The time series of non-cycle of three monitoring points is about 37 days and the hoop stress will be in a stable state after 37 days.
