Description

Technical Field

[0002] The slope deformation monitoring system in the reservoir dam area was developed under the background of combining modern engineering technology with automatic monitoring technology. With the development of human society, the demand for infrastructure such as reservoirs and dams has been increasing, and these facilities are often built in complex geological environments. Due to the uncertainty of geological conditions, slope stability issues have become an important hidden danger to engineering safety. Therefore, in order to prevent geological disasters and ensure the safety of dams and surrounding environments, it is necessary to develop efficient slope deformation monitoring technology. Traditional slope monitoring methods usually rely on manual inspections and simple instrument monitoring, such as using levels, theodolites, etc. The above methods have the following limitations: First, manual monitoring requires a lot of time and human resources. Second, traditional monitoring methods are difficult to achieve real-time data collection and analysis. Therefore, the existing slope deformation monitoring system uses a large number of data collection methods and data analysis methods to perform big data monitoring of slope deformation, which greatly improves the safety of the slope. However, in the existing technology, it is impossible to comprehensively analyze the slope displacement and vibration anomalies caused by water bodies, and it is impossible to accurately evaluate the stability of the dam slope under the impact of water flow and floating objects, which makes it impossible to comprehensively predict and judge the stability of the slope under the impact of future water flow, resulting in the slope being easily damaged by floods. Most of the existing technologies have the above problems; In order to solve the problems raised by the background technology, the present application designs a slope deformation monitoring method and system for a reservoir dam area.
