Method for promoting gradation landslide of landslide mass by adopting active manner

Abstract

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.

Description

Technical field [0001] The invention relates to the field of safety protection and prevention of slopes, in particular to a method for promoting grading of landslides in an active manner. Background technique [0002] Landslides usually bury houses, injure people and animals, destroy fields, destroy factories, schools, roads, water conservancy and hydropower facilities, and even destroy entire towns, as well as power outages, water cuts, work stoppages, and operation of necessary facilities due to landslides. The human sacrifices and property losses caused directly and indirectly by this are immeasurable. [0003] Common landslide prevention is to prevent and control earthquakes and reduce precipitation. By intercepting and bypassing the surface water other than the sliding body, the groundwater in the sliding body is collected and drained to change the mechanical equilibrium conditions of the slope, such as reducing the slope of the slope, reducing the weight of the slope, and fi...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method of actively promoting landslide body graded landslides, which can solve the problem that the existing prevention and control methods cannot eliminate potential safety hazards of landslide bodies, and timely eliminate safety hazards by grading induced landslides, Guarantee the safe operation of necessary facilities, greatly reducing the waste of resources caused by monitoring; reduce casualties, infrastructure paralysis, property losses, etc. caused by sudden sliding of a large number of landslides, and can make appropriate judgments on the type and nature of landslides before taking appropriate measures. The method of inducing landslides greatly reduces the construction cost
