Xiaowan Dam Deformation Monitoring And Analysis Research

Large reservoir dam deformation monitoring method and data processing research has the typical significance in the dam deformation monitoring, the dam deformation monitoring, the research of large hydropower station dam deformation monitoring method, using the prototype monitoring data, analyze its deformation law, scientific analysis of the dam each effect size and influence, the relationship between the amount of time to master its running status and evolution trend, timely detection of the abnormal factors for the social, economic and scientific research, has the vital significance.Based on Xiaowan dam as an example, this paper detailed discusses the work contents of dam deformation monitoring and data processing, design and implement of Xiaowan dam deformation monitoring scheme, monitoring data collection and analysis are studied,specific to do the following work:(1)Systematically and summarized the content and methods of dam deformation monitoring and data processing work.(2)This paper discusses Xiaowan dam deformation monitoring and data processing work.Including:the design of the monitoring programme, benchmark network implementation, horizontal displacement and vertical displacement monitoring the testing process and the calculation of monitoring data processing, etc.(3)To analyze the stability of reference point.(4)Regression analysis of the mathematical model, selecting typical monitoring points, the analysis of water at the dam and dam deformation correlation.(5)The use of a large number of monitoring data, look for a relationship between influence factors and deformation of the dam, to study and analyze the mechanism of dam deformation.Through the analysis and study of xiaowan dam deformation monitoring plan, verify the design parameters of xiaowan dam, shows xiaowan arch dam deformation monitoring scheme scientific and reasonable, reliable monitoring method. Arch dam deformation and water load obvious relevance, the distribution of the dam deformation symmetry and so on, all show arch dam deformation monitoring results reliable,can be a good reaction to a variety of factors that affect the deformation of the dam, effectively protect the safety of dam operation.
