To solve the problems of untimely and low accuracy of tunnel project collapse risk prediction, this study proposes a method of multi-source information fusion.The method uses the PSO-SVM model to predict the surrounding rock displacement.With the prediction index as the benchmark, 1m SMA the Cloud Model (CM) is used to calculate the basic probabili
The contact sponge method is applied on a piece of clay brick.According to the standard, the sponge is moistened with water, applied on the surface of the material by means of a cup, Dipping Bowls and weighted before and after the application.It allows us to determine the amount of water absorbed by the porous material by unit area and unit time.Af
