摘　　要：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 equipment of the Gezhouba third ship lock is simple, only focused on the surface of the ship lock, and the monitoring accuracy cannot satisfy the requirement of the specifications. By renovation of the safety monitoring arrangement, through the selection, rating and calibration, installation and observation of the monitoring equipment, and with preliminary analysis for the deformation law of the third ship lock, the purpose o{ the renovation project is attained, and a foundation is laid for establishing an automatic monitoring system. The observation results by new equipment show that： when the ship lock runs at the full water level, the opening degree of the gate wall is smaller than 2 mm compared with the empty gates; the opening and closing of the left and right vertical joints of the lock chamber, the floor and base surface-connected location is less than 0.1 ram. The ship lock deformation is in good correspondence with the water level of the lock chamber and temperature change, in line with general deformation laws of hydraulic structures.
