Through careful analysis and comparing,we established an intensity parameter of noise source of running trains,which was presented as sound exposure level(L SE0)of an individual car.

Based on them, the intensity parameters and crystal field parameter of Eu3+ were obtained.

The emission, phonon-side band spectra and fluorescence lifetimes of these glasses were studied and the intensity parameters Ω 2 of Eu 3+ were obtained.

Combined with specific calculation example,the influencing degree of linear intensity parameter and non-linear intensity parameters on slope stability was compared and analyzed,the influencing mechanism of two intensity parameters on safety coefficient were pointed at the same time.
