With extracted linear modal parameters (e.g. vibration type, modal frequency etc.), dynamic characteristics of tunnels (including natural frequency, vibration types and damping ratio etc.) are measured based on the back-analysis theory of engineering vibration.
The common stochastic signals in engineering belong to power signals, and their power spectrum is defined as the Fourier Transform of correlation function.
