摘　　要：为监测三峡升船机在施工期、试通航期和运行期的安全状态,同时兼顾验证设计、指导施工等的需要,在升船机内布置了大量监测仪器。分析了三峡升船机在施工期的塔柱变形监测资料,通过统计模型分析,总结了塔柱变形的变化特点和规律。结果表明:受气温影响,塔柱变形和应力应变呈年际变化,塔柱处于稳定的弹性变形状态,满足升船机各机件的运行要求。研究成果可为同类升船机工程施工、设计和资料分析提供参考。In order to monitor the safety status of TGP’s ship lift during construction period,trial navigation period and operation period,and meet needs of verifying design and guiding construction,a large number of monitoring in⁃struments were arranged in the ship lift.This paper analyzed the tower columns deformation monitoring data of the ship lift tower during the construction period,and summarized the deformation characteristics and laws of the tower columns by statistical models.The results showed that the deformation and stress strain of the tower columns varied from year to year,which was affected by the temperature;tower columns were in a stable state of elastic deformation,which met the operation requirements of the ship lift.The research results could provide supports for the construc⁃tion,design and data analysis of similar ship lift projects.
