Abstract:: The debris flow in Taihang Mountain area is the rainstorm activating and dilapidation-landslide evolved style.The forming process contain two parts,that one is rock avalanche and landslide of side wall of valley,and the other is debris flow forming activated by rainstorm.The loosening dilapidation-landslide accumulation caused by forepart rainfall and the flood caused by activating rainfall are two initial activating conditions: the initial activating substance condition and dynamic force condition.Therefore,the debris flow discriminant model based on the the forepart rainfall and activating rainfall accords with the activating conditions of debris flow in Taihan Mountain area.As comparing the true value and the value calculated by the critical rainfall discriminant of debris flow,which is established by the forepart rainfall and activating rainfall of typical debris flow in Taihang Mountain area,the result shows the two values agree with.Thus,it is proved that the critical rainfall discriminant can be used for debris flow prediction.
