Method for monitoring dumping-type collapse disaster

Abstract

The invention discloses a method for monitoring dumping-type collapse disaster. The method comprises the following steps that 1, a monitoring system is constructed; 2, the sizes of dangerous rock bodies and the dip angles of the bottom faces of the dangerous rock bodies in an actual state are input into a data processing center, and the critical dip angles of the collapsed dangerous rock bodies are calculated through a dip angle distinguishing method; 3, a plurality of monitoring devices are arranged at cracks in the rear edges of the dangerous rock bodies, and angle data of the multiple setsof inclined dangerous rock bodies are measured; 4, the multiple sets of angle data measured in the step 3 are sent to the data processing center, the data processing center processes the multiple setsof angle data, and thus the dip angles of the dangerous rock bodies are obtained; and 5, the dangerous rock body dip angles obtained in the step 4 and the critical dip angles obtained in the step 2 are compared and judged in the data processing center. According to the method for monitoring the dumping-type collapse disaster, the criterion that the dangerous rock bodies collapse due to the overlarge dip angles is provided, the collapse disaster can be pre-warned in advance through easy measurement and judgment, and the safety of people and property is ensured.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a monitoring method for toppling-type collapse disasters. Background technique [0002] Collapse generally refers to a sudden and sharp dynamic geological phenomenon of rock and soil falling on a steep slope, that is, a part of a slope with steep terrain and complex geological conditions suddenly breaks away from the parent land under the action of internal and external dynamic conditions. The rapid collapse of rocks is a complex process of multi-factor effects. my country is a country with frequent geological disasters, among which landslides are particularly serious. According to the statistics of the Ministry of Land and Resources, there are more than 8,000 landslide disasters in my country every year, and the direct economic loss is more than 5 billion yuan. 70 cities across the country collapsed and suffered serious geological disasters. [0003] Due to the complex...
