Application of a novel equal-dimension new-information grey model to settlement prediction of earth dam
Fan Wei-xia · Water Resources and Hydropower Engineering · 2005
The combined method of multi-layer recursive modeling and equal-dimension new-information grey modeling for predicting the settlement of earth dam is presented. According to the principle of equal dimension new information in grey theory,this method calculates the parameters of grey model of the settlement prediction through the recursive formula. Based on the parameters calculated, the parameters prediction models can be presented.Then the grey prediction model which reflects time-dependent characteristics of the system is established. The case shows that this method is good to analyze the time-dependent and grey characteristics of the system,and has considerable prediction precision.
