Slope monitoring

1.Slope monitoring monitoring background

Slope monitoring is used as a warning system for areas prone to landslides, providing reliable real-time continuous monitoring of ground movements.For a long time, the safety monitoring technology of slopes in my country has been a weak link in highway construction.Due to the lack of systematic research on safety monitoring technology and no mature experience for design departments to apply, local protection technology can only be used for low-grade highway protection or the experience of other departments to implement local protection.The lack of comprehensive consideration has caused huge economic losses and adverse social impacts, and some even interrupted traffic.The state and local governments have made specific regulations on the health monitoring of slopes.For example, Article 3, Paragraphs 1 and 2 of the "Interim Provisions on Slope Management of Open Pit Coal Mines" stipulate that slope management is included in the deliberation project of safety supervision and bears business security responsibilities.According to annual plan and design and decisions and measures for slope stability, arrangements are made and supervision and inspection are carried out during safety inspection work.

2.Overview of Slope monitoring system

In recent years, slope safety incidents have occurred frequently.In order to promptly understand the slope operation situation and provide early warnings for emergencies, it is urgent to monitor slope safety! Our company's online slope monitoring system can conduct continuous real-time monitoring of slope surface displacement, soil internal displacement, rainfall, soil moisture content, water level changes, etc., make judgments on the overall stability before the disaster occurs, and quickly make early warnings and forecasts for disasters.

3.Main monitoring contents of Slope monitoring

1.Environmental monitoring: rainfall, soil moisture content

2.Deformation monitoring: including surface displacement, internal displacement of soil, relative displacement of the ground surface, and ground cracks

3.Retaining wall monitoring: lateral pressure, inclination monitoring, etc.

4.Groundwater monitoring: pore water pressure monitoring

5.Support structure monitoring: anchor shaft force, anchor cable stress, anti-sliding pile inclination, lattice stress

6.Video monitoring: camera

6.Slope monitoring implementation function

1.Full life cycle monitoring data display: The system integrates the content of slope construction monitoring data, automatically monitors the deformation and environment during the slope operation period, and conducts data storage and analysis to realize full life cycle monitoring of tunnels;

2.Data display during the operation period: including conventional data storage, report download, and data display, the system uses BIM+GIS and aerial survey technology to display the three-dimensional slope model, and display related monitoring content and numerical changes;

3.Leveled early warning: Set different early warning levels according to requirements.When the data is abnormal, the early warning information will be automatically triggered according to the settings, including platform push, text messages and email notification to the corresponding person;

4.Accumulate slope status data: provide necessary decision-making basis for long-term operation, maintenance, maintenance and reinforcement of slopes, and provide basis for assessment of the safety status of slopes after emergencies;

5.Provide reference basis: verify the design and construction theory and construction technology of slopes, so as to improve the slope design and construction technical regulations for relevant geological conditions, and ensure the safety of slope use.
