大坝变形自动监测仪器

Dam displacement automated monitoring instruments

混凝土大坝的变形,尤其是坝基和拱座的变形,是衡量工程安全与否的一个重要指标。变形自动监测仪器与人工测读的仪器相比,具有精度高、时间快的优点。本文参考国外资料,提出测斜仪、钻孔变位计、垂线自动监测仪等三种国内外正在试用的电子仪器。将有助于提高并改善大坝设计的经济性和安全性。

Concrete dam displacement, especial for dam foundation or arch support, is an important target to judge the safety. The displacement antomated monitoring instruments are furnished with high accuracy and quick acquisition when compared with manual readings This paper describes tiltmeter, borehole displacement instrument and automated plumbline mon- itoring instrument taking from foreign information. These electronic instruments, now operating at home and abroad, are beneficial for enhancing and improving economy and safety in dam design.
