High slope safety online monitoring system
Due to the heterogeneity of rock properties, the complexity of geological structure, and the complex effects of mechanical action and mechanism, the high-steep slope engineering project has strong uncertainty and complexity, and the mechanism of slope deformation instability is complex. On this basis, the preliminary design and management measures for slopes often have the inability to fully understand the working conditions and safety conditions of slopes. In addition, the construction of slopes is a dynamic process, and the boundary conditions are heterogeneous and different in degree. Anisotropy, the judgment and prediction of this non-deterministic and dynamically changing slope deformation instability need to rely on effective slope deformation monitoring, timely analysis and processing of monitoring data, so as to achieve dynamic design and information construction in time. Effective prevention and control.
Slope Safety Monitoring System Design Ideas
1. The slope monitoring system must fully consider the actual characteristics of the project, reasonably set up relevant monitoring projects, and scientifically arrange monitoring sections and points. It is necessary to ensure the representativeness of the monitoring sites and reflect their specificity to ensure that the system is effective and accurate. It reflects the displacement, settlement and deformation of the slope, monitors the safety and protective effect of the slope structure and protective structure, and monitors the seepage of the slope and groundwater changes.
2. It is required that the slope monitoring system be able to respond to abnormal signs in real time, promptly perform early warning on points where abnormal phenomena occur, and provide real-time and effective feedback warning information!
3, slope monitoring system must have real-time, high reliability, easy operation and so on.
