葛洲坝3号船闸原有安全监测设施较为简单,仅集中在闸面,且监测精度难以达到规范要求,通过安全监测更新改造布置和监测仪器的设备选型、率定检验、埋设安装及观测,以及对3号船闸变形规律的初步分析,说明更新改造工程达到了预期目的,为建立监测自动化系统奠定了基础。新的监测仪器观测结果表明,船闸运行过程满水位时,相对于空闸闸墙张开量不足2mm;闸室左右纵缝、底板与建基面结合部位的开合小于0.1mm,其变形与闸室水位、气温升降有着良好的对应关系,符合水工建筑物一般变化规律。
The original safety monitoring facilities of Gezhouba No.3 ship lock are relatively simple and concentrated only on the gate face, and the monitoring precision can not meet the standard requirements. The equipment selection, calibration test, buried installation and observation by means of safety monitoring and reconstruction and monitoring equipment, The preliminary analysis on the deformation of No.3 ship lock shows that the renovation and reconstruction project has achieved the expected purpose and laid the foundation for the establishment of a monitoring and automation system. The observation results of the new monitoring instruments show that when the ship lock is running at full water level, the opening of the gate relative to the empty gate wall is less than 2mm; the longitudinal seam at the gate chamber and the joint of the base plate and the base surface open and close less than 0.1mm; Water level, temperature rise and fall have a good correspondence, in line with the general changes in hydraulic structures.
