变电站沉降监测技术应用与案例分析OA

Focuses on the settlement hazards in the equipment foundations of the 66 kV equipment area at a 750 kV substation,which have emerged during long-term operation.Based on the trigonometric leveling measurement technology of total station and the technical requirements of the"Code for Deformation Measurement of Buildings",a systematic settlement monitoring network was established:relying on 9 highly stable reference points and 204 precisely arranged monitoring points,a closed-loop observation route design and indirect adjustment algorithm were adopted to accurately calculate multi-period monitoring data;through Surfer software,spatial modeling and multi-dimensional analysis were conducted,generating contour maps,shaded relief maps,etc.,quantitatively characterizing the spatial heterogeneity of the site settlement.A systematic settlement monitoring and analysis of the substation site and equipment foundation was carried out,identifying high-risk settlement areas,providing a scientific decision-making basis for the safe operation and maintenance of the substation throughout its life cycle.The related technical framework has reference value for the settlement prevention and control of ultra-high voltage transmission and transformation projects.
