Media Monitoring

1. Background of Slope monitoring

Media Monitoring performs health diagnosis of subway tunnels through deformation monitoring, force monitoring, groundwater monitoring and environmental monitoring.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, there is no mature experience for the design department to apply, so only the protection technology of low-grade highways can be used.Or draw on the experience of other departments to implement local protection, lacking comprehensive considerations, resulting in huge economic losses and adverse social impacts, and some even disrupted transportation.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 the Management of Slopes in Open-pit Coal Mines" stipulate that slope management work shall be included in the agenda of safety supervision and shall have business responsibilities.Security Responsibilities.Make arrangements and conduct supervision and inspections during safety inspections based on annual plans and designs as well as slope stabilization decisions and measures.

2.Overview of Slope monitoring system

In recent years, slope safety incidents have occurred frequently.In order to understand slope operation conditions in a timely manner and provide early warning for emergencies, slope safety monitoring is urgent! Our slope online monitoring system can conduct continuous real-time monitoring of slope surface displacement, internal soil displacement, rainfall, soil moisture content, water level changes, etc.to make judgments on the overall stability before disasters occur and quickly make decisions.Early warning and forecasting of disasters.

3.Main monitoring content of Slope monitoring

1.Environmental monitoring: rainfall, soil moisture content

2.Deformation monitoring: including surface displacement, internal soil displacement, surface relative displacement, and ground fissures

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

4.Groundwater monitoring: pore water pressure monitoring

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

6.Video monitoring: camera

5.Basis for Slope monitoring

"Slope Engineering Survey Specification YS/T 5230-2019"

"Technical Specification for Building Slope Engineering GB50330-2013"

"Geotechnical Engineering Monitoring Specification YS5229-96"

"Specifications for Exploration of Landslide Prevention and Control Engineering DZT0218-2006"

6.Slope monitoring implementation function

1.Full life cycle monitoring data display: The system integrates the slope construction monitoring data content, conducts automated online monitoring of the deformation and environment of the slope during the operation period, and performs data storage and analysis to achieve full life cycle monitoring of the tunnel;

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

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

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

5.Provide reference basis: verify the design and construction theory and construction technology of slopes, thereby improving the technical regulations for slope design and construction related to geological conditions and ensuring the safety of slope use.
