Analysis of published data on the thirdand fourth-order moments of vertical velocity in the atmospheric boundary layer is performed, and it is shown that turbulence is non-Gaussian even when almost symmetric. It is also proposed that the relationship between thirdand fourth-order moments depends on stability. New data from a wind tunnel experiment roughly support this hypothesis. The analysis p...

The stability of tunnel is greatly affected by the changes in volume and strength swelling loess caused humidification. Quantitative reflection influence humidification on mechanical model has important engineering significance for design support structures. Based fact that parameters related to are functions water content, content was introduced into classical surrounding rock–support model, a...
