大化大坝监测系统更新改造及自动化系统设计

大化水力发电厂大坝原监测系统所设置的监测项目均采用人工观测方法,限于仪器的精度和外界环境对人工观测的影响,部分项目的精度难以满足《混凝土大坝安全监测技术规范》(以下简称“规范”)的要求。结合大化水电厂大坝的实际情况,对照“规范”要求,根据目前自动化监测技术的发展水平,对大化大坝的监测系统提出较完善的方案,在此基础上基本实现了自动化观测。

DESIGN FOR REFORMATION OF MONITORING SYSTEM AND THE AUTOMATIC MONITORING SYSTEM AT DAHUA DAM

In the original monitoring system of the Dahua Dam, all the items were observed manually. Because of the low precision of manual monitoring instruments and the influence of the environment, the observation precision of some items could not satisfy "The Technical Criteria of Concrete Dam Safety Monitoring" (SDJ336 -89) issued by the government of P. R.C.According to the practical situation of Dahua Dam, the requirements of "SDJ336 - 89". and the development of automatic monitoring technique, a design scheme for Dahua Dam safety monitoring is formulated, and automatic monitoring is realized.
