Abstract

In order to predict subgrade settlement under the influence of uncertain factors, this paper constructed a combined prediction model of subgrade settlement based on set pair analysis theory and statistical decision idea. Firstly, the single-item prediction model was selected, and the predicted value and the measured value were constructed as a set pair according to the prediction results of the single-item prediction model. Then, the normal distribution theory was used to determine the set pair relationship partition standard, and the combined weight coefficient was determined based on the connection number to realize the optimal combination of prediction information. Finally, the combined prediction model was proposed by the prediction error evaluation, and the effectiveness of the combined prediction model applied to the subgrade settlement was verified by the settlement data of a subgrade.
