Problems solved by technology

At present, the common data analysis method is the stepwise regression model, which has strict requirements on the distribution of samples, the independence between dependent variables and the size of the dependent variable, but the actual slope monitoring data are difficult to meet the above requirements

Embodiment Construction

[0053] The present invention will be described in further detail in conjunction with the accompanying drawings and specific embodiments.

[0054] The new method for data analysis of embankment slope deformation monitoring of the present invention includes the following aspects:

[0055] 1. Regression analysis based on orthogonal decomposition

[0056] Monitor the displacement of the embankment slope and the key influencing factors affecting the displacement of the embankment slope. The key influencing factors affecting the displacement of the embankment slope are the independent variables, and the displacement of the embankment slope is the dependent variable. The data matrix is ​​decomposed on the basis of standardization to obtain the relationship between the characteristic orthogonal base and the independent variable, and then use the characteristic orthogonal base and the dependent variable to perform regression analysis, and then obtain the relationship between the depend...

Abstract

The invention discloses a novel analytical method of deformation monitoring data of a dam slope. Dam slope displacement and a factor influencing the dam slope displacement are monitored, monitoring data are selected, a regression analysis based on proper orthogonal decomposition is carried out to obtain a feature orthogonal basis of proper orthogonal decomposition; quantile regression analyses are carried out on the feature orthogonal basis and the damp slope displacement to obtain regression equation parameters of all quantiles, and then original data substitution is carried out to obtain a quantile regression equation of the original data; and then changing situations of regression equation estimation values of independent variables under different quantiles as well as whether the regression equation estimation values pass the significance test successfully are analyzed and the influence degrees on the dam slope displacement by the independent variables are determined. According to the invention, the method has the great significance in early-warning model establishment for a slope of a dam, slope prediction and forecasting method providing, and slope sensitive influence factor analyses.

Description

technical field [0001] The invention relates to a new method for analyzing data of embankment slope deformation monitoring, which belongs to the technical field of hydraulic engineering slope deformation monitoring. Background technique [0002] There are 98,002 reservoirs in my country, including 756 large ones (including 127 large (1) and 629 large (2) type), 3,938 medium-sized, and 93,308 small-sized reservoirs; the flow through the gate is greater than 5m 3 / s has 97,019 sluice gates, including 860 large ones, 6,332 medium ones, and 89,827 small ones; the embankment is about 413,679km. Many of the above-mentioned water conservancy, hydropower, water transportation and transportation projects include or contain earth slope projects. Slope instability failure is the main form of earth dam failure, and it is also an important factor affecting the safety of similar projects, which seriously affects the safety of the project and related personnel and facilities. From 1954 t...
