Application method of multi-dimensional and multi-level analysis method in concrete dam safety monitoring and analysis system platform

The invention provides an application method of a multi-dimensional and multi-level analysis method in a concrete dam safety monitoring and analysis system platform, which comprises the following steps of: 1, classifying different dimensions and different types of monitoring physical quantities obtained by monitoring a reservoir dam by using an SVM classification principle, judging whether the monitored physical quantity is a gross error or not by using a Pauta criterion; step 2, performing first-layer data analysis on the processed monitoring physical quantities with different dimensions and different types, realizing data reorganization, and displaying the data on a platform; 3, in combination with inversion analysis, performing second-layer data analysis on structural analysis and calculation of the dam by adopting a strength theory; step 4, establishing a monitoring model to carry out third-layer data analysis, and ensuring short-term prediction precision; and step 5, establishing a medium-and-long-term p
