摘要
两河口水电站大坝为300 m级高砾石土心墙坝,建坝于高原高寒地区。特殊的环境条件对监测仪器的耐久性、可靠性及适应性提出了很高的要求。柔性测斜仪为安全监测新仪器,在水电工程中的应用较少,在300 m级高土石坝中的使用更是国际首创。自2017年以来,柔性测斜仪在两河口水电工程中已布设并安装了10套,仪器运行情况整体良好,监测成果能够反映出所测部位的真实变形,所取得的监测成果在服务该工程的同时,可对同类型工程的安全监测起到指导作用。
A gravel soil core dam with height of 300m is built in the plateau and cold area for Lianghekou Hydropower Station.The special environmental conditions place high requirements for the durability,reliability and adaptability of monitoring instruments.Flexible inclinometer is a new instrument for safety monitoring which is rarely used in hydropower projects,and its application in monitoring of gravel soil dam with height of 300m is internationally unprecedented.Since 2017,10 sets of flexible inclinometers have been deployed and installed in Lianghekou Hydropower Project,those instruments are operating well and the monitoring results reflect the real deformation of the measured parts.The monitoring results not only serve the project,but also play a guiding role in the safety monitoring of similar projects.
