The invention relates to the technical field of hydraulic prediction systems, in particular to a hydraulic structure stress deformation prediction system based on a finite element method. The system comprises a safety supervision data acquisition module, a data regression analysis module, a data association analysis module and an intelligent prediction module, the system constructs a statistical model through the safety supervision data acquisition module, and then processes the statistical model through the data regression analysis module to obtain a multiple correlation coefficient R and a residual standard deviation S; the data association analysis module processes the data acquired by the safety supervision data acquisition module to obtain a safety state index grade system; the intelligent prediction module obtains an optimal prediction period through a correlation coefficient calculation formula on the basis of a correlation relation between monitoring data obtained through processing of the data correlation analysis module and the safety state index grade system, and constructs a PSO-SVR model; according to the system, the stress deformation of the hydraulic structure can be effectively, quickly and accurately processed, and the future change condition of the hydraulic structure can be accurately predicted.
