| With the advancement of technology and national economic development, both the scale and the speed of Water Resources and Hydropower Engineering construction are in fast growth. Along with that. project accidents occur more and more frequently. So the dam deformation monitoring is particularly important. According to the relevant specification in China, dam safety deformation monitoring is an important project that must be measured and has been paid extensive attention in Water Resources and Hydropower Engineering. In this thesis, the author takes the deformation monitoring project of the Shiling scenic area of Chengdu Qinglonghu earth-rock dam as an example, focuses on both the practical significance and theoretical analysis and gives a systematic study of the content, methods, characteristics and laws in the earth-rock dam deformation monitoring.This thesis includes the following parts:First of all, the author explains the significance of deformation monitoring and mainly highlights the importance of deformation monitoring through the introduction of typical accidents. At the same time, the thesis also sums up the data processing research of the deformation monitoring. It also introduces new methods in the deformation monitoring; secondly, it also gives a close analysis to the contents of earth-rock dam deformation monitoring, monitoring program design, the commonly used methods in deformation monitoring, anlysis and an overview of the whole process of dam deformation monitoring:then the theis discusses in detail the dam deformation monitoring project in dam deformation monitoring which including:the design of the monitoring project, the basic process in the survey process benchmark network, the process in the horizontal displacement monitoring, the process in the vertical displacement monitoring and the analysis of the monitoring data etc.; Finally, the thesis gives a deformation analysis to the deformation monitoring data which including:the stability analysis, establishing a mathematical model using the statistical software SPSS 13.0 for dam deformation.Through the above discussion. the following conclusions are drawn:1, the deformation monitoring process designed in Qinglonghu earth-rock dam is scientific and workable and the monitoring results are reliable; 2, the thesis proposes the use of the method of mean gap to analyze the stability of the monitoring network, and uses the significant fixed point deformation analysis method to judge the significance of the situation, so as to provide stability analysis of various orders of magnitude; 3, the establishment of a mathematical model for deformation prediction, using statistical analysis software-SPSS, is feasible and it can meet the requirements of dam deformation prediction. In summary. this research on the theories of earth-rock dam deformation monitoring and the collection of data. data analysis methods, its content and specific measures used in the program can provide a reference for future similar work. |
