Multi-parameter model dynamic early warning method based on landslide three-dimensional monitoring

Abstract

The invention discloses a multi-parameter model dynamic early warning method based on landslide three-dimensional monitoring, and the method comprises the steps: carrying out the preliminary evaluation of the current stability of a main monitoring object according to the deformation characteristics of a landslide monitoring region, and obtaining a preliminary evaluation result; setting an early warning criterion threshold according to the preliminary evaluation result, the landslide disaster development history and the development mechanism; constructing a multi-parameter early warning model according to the type selection of the monitoring equipment of the main monitoring object in combination with the main induction factors of the landslide disaster; the early warning criterion threshold and the multi-parameter early warning model are dynamically adjusted, and an abnormal strategy is set to reduce the false alarm rate; and when the monitoring value reaches the dynamically adjusted early warning criterion threshold range, triggering the multi-parameter early warning model, and sending landslide early warning information. Through dynamic adjustment of early warning criteria and models, along with increase of monitoring information and clarification of development trends, the precision of the monitoring and early warning models can be improved; the research of a geological disaster monitoring and early warning system is facilitated, and the accuracy of geological disaster monitoring and early warning is improved.

Description

technical field [0001] The invention belongs to the technical field of geological disaster monitoring and early warning, and in particular relates to a multi-parameter model dynamic early warning method based on three-dimensional landslide monitoring. Background technique [0002] Geological disasters such as landslides, landslides, and debris flows widely exist in mountainous and hilly areas in my country, posing huge hidden dangers to economic and social development and the safety of people's lives and properties. Accurate landslide disaster monitoring and early warning is an important way to improve disaster prevention and mitigation capabilities. As a complex system engineering, it not only involves landslide disaster site investigation, development mechanism analysis, and stability evaluation, but also includes monitoring equipment selection, early warning criterion threshold setting, early warning model design, etc. [0003] The common regional landslide disaster moni...
