plumb-line

With the reconstruction of the plumb line monitoring system of Dongjiang dam from a centralized structure to a distributed structure, the automatization degree, reliability and real-time performance of the system are improved greatly.

东江拱坝垂线自动监测系统由集中式改为分布式后,其自动化程度及可靠性、实时性等都得到很大的提高,获得的有规律性的观测资料为保证大坝安全运行提供了依据。

Employing the three?dimensional FEM and unit equivalent temperature method, and combining with observed by plumb line information and dam thermometer monitoring data of Shuikou,the deterministic models of horizontal displacement are proposed.
