Description

Technical Field

[0001] This invention relates to the field of slope safety monitoring technology, and in particular to a method and system for early risk coverage monitoring of highway slope safety. Background Technology

[0002] As a crucial component of transportation infrastructure, highway slopes are susceptible to landslides and collapses due to various factors such as geological conditions, climate, and operational loads. These geological hazards severely threaten highway safety, causing significant economic losses and casualties. Currently, highway slope monitoring primarily employs the traditional "risk level-based deployment" model, which suffers from the following technical shortcomings: Low accuracy of monitoring deployment: Traditional monitoring relies heavily on manual site selection, which does not fully take into account core features such as slope topography and soil distribution, making it easy to have monitoring blind spots. In addition, unreasonable equipment deployment locations lead to high equipment wear and tear rates and unstable data transmission, making it impossible to achieve full-area coverage monitoring. Insufficient accuracy in risk prediction: Existing prediction models mostly use single time series data for fitting, ignoring the influence of three-dimensional geological features of slopes. They have weak ability to predict slope risks under the coupling of multiple factors, large prediction deviations, and cannot identify early risks in advance. The early warning and response measures are not targeted enough: the early warning triggers rely on the absolute value of a single monitoring indicator without taking into account the difference between the predicted value and the real-time value and the rate of change of the indicator. This makes it difficult to distinguish the risk level, resulting in overly crude response measures that cannot achieve accurate early warning and hierarchical control. Poor coordination throughout the entire process: The monitoring deployment, risk prediction, and early warning response are all independent of each other, lacking effective data flow and collaborative optimization mechanisms, making it impossible to form a closed-loop management and control system, which affects monitoring efficiency and risk prevention and control effectiveness.

[0003] To address these issues, there is an urgent need for a comprehensive early-stage risk monitoring method and system for highway slope safety. Summary of the Invention
