Abstract: The significance of deformation monitoring at foundation of gravity dam was expounded, the application of non-buoy wire alignment for CFRP and its feasibility to use in slope sections were discussed, and horizontal displacement monitoring at gravity dams was extended. Further, monitoring of horizontal displacement inner earth-rockfill dam by serial rod displacement meter was advanced, and the possibility of construction of monitoring system with air laser alignment for horizontal displacement inner earth-rockfill dam was proved. As well, disadvantages in existed settlement monitoring systems were analysed. It is necessary to adopt water level settlement gauges and transom type settlement gauges in settlement monitoring systems for high face-slab rock-fill dams, and this combination is an important guarantee for construction quality of concrete face and safety operation.

摘要： 简要阐述了重力坝坝基水平位移监测的重要性，讨论了CFRP无浮托引张线系统的应用范围，重点论述了将无浮托引张线系统应用于坝基斜坡坝段的可行性，拓展了重力坝坝基水平位移监测的范围；提出了采用串联杆式位移计监测土石坝的坝内水平位移，论证了应用大气激光准直系统构建土石坝坝内水平位移监测自动化系统的可能性；分析了现有土石坝沉降监测布置的局限性，探讨了在高面板堆石坝沉降监测中采用水管式沉降仪和横梁式沉降仪的必要性，并指出这种组合布置是确保高面板堆石坝混凝土面板施工质量和安全运行的重要保障。
