Safety Monitoring And Engineering Treatment Measures For The Underground Plant Of A Pumped Storage Power Station In Pushi River

In this paper, combined with pumped storage power station project in PuShiHe, thedesign of hydraulic structure safety monitoring projects, implementation, the sorting ofsafety monitoring data, integrate and analysis methods are introduced.By displacement,stress and water pressure, etc. Various sensors installed in a location to be measured, foron-line monitoring of modern monitoring methods, collection of large underground cavernconstruction in the process of surrounding rock deformation and the stress release and otherinformation.For engineering information collected, the use of measuring value influencefactor method, comparison method, graphic method and eigenvalue statistics and othermodern analysis method, calculation and analysis of various sensors measured valuequantity change.To guide the construction according to the analysis results, optimizationdesign, information construction, do "design-construction-monitoring-optimizationdesign-" such a process, not only ensure the engineering quality and safety, and avoidswaste caused by the conservative design, save the project investment.The article detailedanalysis of the large underground engineering excavation process, the internal deformationof surrounding rock, of deformation and stress of surrounding rock release, form, themechanism of phase change and the change process, through the analysis of monitoringdata, points out that the monitoring of the part of the physical quantity to exceed bid andhidden trouble in safety engineering, and part of being safe hidden trouble researchengineering treatment measures and implementation, through monitoring results,demonstrate the rationality of the analysis of engineering treatment measures, to evaluatethe running state of the whole project.
