Multi-parameter and three-dimensional monitoring method and monitoring probe for reservoir bank of water-level-fluctuating zone

Abstract

The invention provides a multi-parameter and three-dimensional monitoring method for a reservoir bank of a water-level-fluctuating zone. The multi-parameter and three-dimensional monitoring method comprises the following steps: setting monitoring lines in a rock-soil mass to be monitored; acquiring lateral displacement data and angle data which are transmitted between a displacement sensor and an angle sensor in each monitoring point; drawing a three-dimensional picture showing initial locations of all the monitoring points according to the location of each monitoring point under an initial state, obtaining the displacement offset of each monitoring point according to the acquired lateral displacement data and angle data, and drawing a three-dimensional picture showing locations of all the monitoring points at the same time; comparing three-dimensional pictures showing locations of all the monitoring points at different time to evaluate the stability of the rock-soil mass to be monitored. The multi-parameter and three-dimensional monitoring method has the advantages that through monitoring of horizontal displacement and an inclined angle of a landslide mass, three-dimensional monitoring on the landslide mass can be realized.

Description

technical field [0001] The invention belongs to the field of data monitoring, and in particular relates to a multi-parameter three-dimensional monitoring method and a monitoring probe for a bank of a drawdown zone. Background technique [0002] Water-fluctuation zone is a special area formed by periodic water level fluctuations in lakes, rivers, reservoirs, etc. Long-term and effective monitoring of the water-fluctuation zone on the banks of rivers and reservoirs is carried out to strengthen the research on geological hazards and engineering rock mass stability. It is of great practical significance to scientifically understand the stability and danger of the slopes and dangerous rock masses in the drawdown zone of river banks, and to formulate medium and long-term plans for disaster prevention and mitigation of river banks. At present, the common monitoring method of the water-fluctuation zone relies on manual inspection or monitoring based on single-parameter testing instr...

AI Technical Summary

Problems solved by technology

At present, the common monitoring method of the water-fluctuation zone relies on manual inspection or monitoring based on single-parameter testing instruments. However, due to the huge area of ​​the water-fluctuation zone in China, and the single-parameter landslide monitoring often leads to misjudgment of landslides, for example, when the monitoring end follows the landslide body When movement occurs, the horizontal displacement parameter cannot simply be used as the basis for landslide judgment, but the changes of other parameters should be considered comprehensively to conduct a comprehensive analysis of the landslide situation of the rock and soil mass

Therefore, there is still a lack of an effective multi-dimensional dynamic monitoring system that integrates multiple factors
