Adaptive expansion slope stability intelligent monitoring early warning system

Abstract

The invention discloses an adaptive and extended intelligent monitoring and early warning system for slope stability, which includes a geographic information collection module, a three-dimensional modeling module, a scheme selection module, a data collection module, a statistical analysis module, and an early warning module. The geographic information collection module is used for collecting The geographic location information of the monitoring area c is used to generate a GIS data model. The 3D modeling module is used to generate a 3D model of the monitoring area based on the pictures in the monitoring area. The three-dimensional model of the area determines the slope type, landslide risk, and determines the monitoring point, monitoring plan, and early warning plan. The data acquisition module is arranged at the monitoring point to collect the monitoring data of the monitoring point. The statistical analysis module is used to process the monitoring data based on the monitoring data. Generate various statistical data, and the early warning module determines the early warning model, early warning level, and disposal plan based on the monitoring data and statistical data. The invention can effectively reduce risks such as landslides.

Description

Technical field [0001] The invention relates to an adaptively extended intelligent monitoring and early warning system for slope stability, which belongs to the technical field of water conservancy and hydropower engineering. Background technique [0002] Slope is a general term for natural bank (inclined) slope and artificial slope. For slopes under certain topography and geological conditions, due to changes in external factors (such as vegetation damage on the slope surface, long-term water infiltration, cutting slopes or stacking, etc.), the original mechanical equilibrium conditions are destroyed and the slopes are Under the combined action of its own weight or other loads, the unstable body is an unfavorable geological phenomenon that slides downwards along a certain relatively weak surface (belt) in a slow, intermittent, and sometimes even sudden manner, namely Landslide phenomenon. When a landslide occurs, it can cause death, traffic interruption, river blockage, burial...

Problems solved by technology

[0003] In order to deal with landslides and slope instability, currently more effective methods are: (1) Use existing monitoring instruments (extensometer, slope measuring instrument, etc.) In some cases, in order to achieve the purpose of effectively monitoring the soil state, the monitoring instruments must be spread over the entire monitoring area. The cost is huge and the effective monitoring instruments are limited, resulting in a serious waste of cost and resources; (2) through theoretical calculations, for all Perform slope stability analysis on possible sliding surfaces to obtain the safety factor and determine the critical sliding surface with the smallest safety factor; this method is only applicable to the specific sliding surface of a specific project. , it is still difficult to determine and calculate the stability of all possible sliding surfaces in a certain area. At the same time, the stability of landslides under different conditions (such as: rainstorm, earthquake and construction, etc.) may be quite different, and the specific situations need to be discussed by category , so the method is not reproducible in different projects
