Analysis Of Deformation Monitoring Data Of Gutian Creek Two Dam

China has richly endowed by nature of hydropower resources.With the rapid development of national economy,We has made remarkable achievements in the field of hydropower construction.The total hydropower installed capacity and annual power output ranked first in the world.A large number of world-class high dam will be built or will be run into,more large projects are also in the planning preparation.The dam will bring significant social and economic benefits to the country during normal operation.However,once the security problem,suddenly releasing water flow will bring crowning calamity to the downstream people.It will bring unimagined huge losses to the national economy and social development.In order to accurately understand the dam operation characters,first,you must get attention from the management,coupled with effective artificial inspection and observation instrument monitoring method.It can make the dam monitoring work to achieve the purpose of nip in the bud.Timely analysis of monitoring data is the most important way to further understand the health status of the dam.During the normal operation,the effect of the volume change is slow and small,and there are rules to follow.When changes appear obvious abnormalities,it often indicates that the dam has unsafe factors.Now we should analyze the reason,clear the exception,and take corresponding measures.So it is very important to analyze the dam monitoring data regularly.This paper mainly introduces the present situation and development of dam safety monitoring data analysis theory at home and abroad,the main steps and general methods of monitoring data analysis.Based on the horizontal displacement and vertical displacement monitoring data of the Gutian Creek Two Dam,the analysis work is carried out.This analysis mainly adopts the following technical route:the monitoring model has been established based on the monitoring data of qualitative analysis and spatio-temporal analysis.Then we can analyze the changes and influence factors of each measurement quantitatively by separating the components of typical years in amplitude model with these models.Then the change law of this monitoring project of the horizontal displacement and the vertical displacement of dam is made a comprehensive analyse.The operation state of the deformation monitoring system of Gutian Creek Two Dam is made a comprehensive evaluation.On this basis,the iversion of the elastic modulus of the typical dam comprehensive is carried out by the statistic model,hybrid model and the finite element analysis results.
