Research on the method and system of evaluation model for early warning based on ground pressure monitoring information

摘要

In order to achieve the purpose of early warning, a scientific and reasonable evaluation system of early warning is required to be established.Based on multi-source information obtained by monitoring surrounding rocks, this paper proposes three parameters as early warning indicators, namely, rock displacement, deformation rate and acceleration for deformation.First, it made a quantitative analysis and evaluation of the monitoring data, and used a variety of data smoothing methods or wavelet analysis for the diagnosing of monitoring data to determine the criteria for the safety of surrounding rocks.Then, it gave a consideration to the genetic mechanism of rock deformation and combined it with mathematical and statistical methods to establish a forecast model of monitoring data, thereby getting a system for monitoring, warning and evaluating the ground pressure.It has extremely important theoretical and practical significance for correctly predicting rock failure, effectively preventing accidents, and successfully warning accidents.
