On the base of probabilistic and statistics results of joints and cracks, the Author modifies Block Theory. The sliding probability of Key Block is I A RSTR A CT F2 ? 5.It is put up forward that GM(l,1) Model to predict Amount of rainfall, and Markov Chain to modifY GM( 1,1 )predicting result, and then a theoretical predicting Model of amount of rainfall is firstly built. This model is applied in a situ example. It is proved that the model is very useful to predict amount of rainfall ,when ordinal array of Amount of rainfall changes in unexact index rule.
