杆式沉降计作为土石坝内部沉降监测仪器,解决了土石坝沉降监测难以实现自动化的难题。杆式沉降计观测简便,替代水管式沉降计可减少对坝体施工的影响,并省去测控装置、观测房和大量的土建工作。总结了杆式沉降计的研制背景、原理结构和在工程实际应用中取得的成果。 As a settlement monitoring instrument inside the earth-rock dam, the rod-type sedimentation meter solves the difficult problem of automatic monitoring of the earth-rock dam settlement. Rod-type sedimentation station observation is simple, alternative to the water pipe settlement meter can reduce the impact on the dam construction, and eliminating the need for measurement and control devices, observation rooms and a large number of civil works. Summarized the research background, principle and structure of the rod-shaped sedimentation meter and the results obtained in the practical application of the project.
