摘要： 大坝水平位移监测控制网一般采用边角网，网点间边长倾斜改正的高差可采用精密水准法或三角高程法观测，高差较大、边长较长的大型边角网宜采用精密水准法观测，中小型大坝等工程边角网可采用平差后的三角高程进行倾斜改正。通过控制网网型设计的优化及现场观测方法的改进，采用合适的监测仪器，可以达到预期目标，满足规范及工程安全运行的要求。
关键词: 中小型大坝, 水平位移监测控制网
Abstract: Triangulateration network is usually used in horizontal control network. The height difference of tilt correction can be observed by precision leveling or trigonometric leveling. For triangulateration network with large height difference and long length, precision leveling is recommended, while for the horizontal control network of small and medium dams, adjusted trigonometric leveling is recommended for tilt correction. By optimization of the network and the observation method as well as the adoption of proper monitoring instruments, the monitoring goals can be realized which meets the requirements of regulations.
Key words: small and medium dams, horizontal control network
