| Abstract: | This paper studies the core-wall settlement of Nuozhadu core-wall rockfill dam in the construction period and describes the establishment and analysis of the theory and procedures for statistical regression model.Based on traditional statistical model,different models are established by changing the forms of model factors;comparative analysis of the results of model application is made so as to determine the appropriate and better statistical model form.Through the measured data to establish the model and evaluate the prediction of different models.The results indicate that the accuracy of model prediction is high and it is more convenient than the traditional model.Therefore,it can be used as a tool for settlement analysis for Nuozhadu project in the construction period and providing a reference for similar projects. |
