葛洲坝水利枢纽安全监测自动化的实施

APPLICATION OF SAFETY MONITORING AUTOMATION SYSTEM IN GEZHOUBA PROJECT

葛洲坝水利枢纽安全监测自动化从１９８１年开始实施，８０年代试验使用了７套安全监测自动化装置，９０年代以来安装试用了３套安全监测自动化系统，自动监测范围涉及到坝体与基础水平位移、内部应力应变、坝体温度与接缝张合、基础渗流状态等监测项目，其中，有成功的经验，也有失败的教训。目前，已经有３套比较先进的自动化监测系统投入使用。文章介绍了葛洲坝大坝安全监测自动化实践过程，自动化监测设备运行现状及评价。指出实施大坝安全监测自动化应该注意的问题。

In the Gezhouba project,the safety monitoring automation system has been applied since 1981.In 1980s,seven sets of safety monitoring atuomation system were tried.In 1990s,three more sets have been put into trial operation.The scope of automatic monitoring involves horizontal displacement in the structure and foundation,stress and strain of the structure, temperature and change of joint in the structure,permeability of the foundation and so on.Some of the applications are successful but some are not.At present,three sets of advanced automatic systems are applied.The paper introduces the practice in safety monitoring automation in Gezhouba project and the present situation of operation of the automatic monitoring systems ,and it also gives several suggestions about application.
