务川沙坝水电站坝体外部变形监测分析

介绍了贵州省务川县沙坝水电站碾压混凝土双曲拱坝坝体外部变形监测控制网布置情况，通过对工程下闸蓄水初期和运行期坝体外部变形监测资料的分析，初步掌握了建筑物整体位移变形情况和运行情况，为沙坝水电站的正常运行管理提供必要的决策信息。对于同类工程安全监测系统的设计、观测及监测数据分析均有借鉴意义。

Analysis of Sha Dam Hydropower Station Exterior Deformation Monitor

This article mainly introduces the arrangement of monitoring control network of Wuchuan County rolled concrete double-curvature arch sandbank hydroelectric station in Guizhou Province. By close comparison and analytic study on the data of initial and runtime water impoundment moment under engineering condition, the article achieves primary knowledge of deformation and operation on the dam’s integrated displacement, and gives information of decision-making to the team manager. The result could also produce some use for reference to the similar projects on safety automatic monitoring system designing, monitoring and data analyzing work.
