新型土石坝沉降监测仪器杆式沉降计的应用

Application of a New Earth Dam Interior Settlement Monitoring Instrument-Rod Settlement Gage

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 in the interior of an earth dam, the rod settlement gage can meet the requirements of monitoring the interior settlement of an earth dam in an automated and convenient way. It can reduce the effects on dam construction, and cut down the unnecessary cost of civil engineering of observation rooms and other related works. This paper summarizes the background of development, the principle and structure of the rod settlement gage and the results of its engineering application.
