The invention discloses a method for promoting gradation landslide of a landslide mass by adopting an active manner. The method comprises the following steps that 1, the location of each part of a landslide is determined; 2, zoning processing is conducted, specifically, according to the size of the landslide mass on a landslide bed, the landslide mass is divided into a plurality of sliding zone masses in the landslide direction; 3, holes are drilled; 4, an edge sliding zone mass slides off, specifically, one or more combinations of micro-explosion induction, water explosion induction, foamingagent application induction, high-pressure gas injection induction and non-contact induction are adopted for the holes drilled in the step 3, and thus the edge sliding zone mass slides off the landslide bed; and 5, the step 4 is repeated, and each adjacent sliding zone mass slides off the landslide bed one by one. According to the method for promoting gradation landslide of the landslide mass by adopting the active manner, the problem that existing prevention methods cannot eliminate potential safety hazards of the landslide mass can be solved, and the safety hazards are eliminated in time bythe gradation induction landslide.
