| Abstract: | Settlement of earth-rockfill dam is mainly influenced by aging deformation and regression model is usually adopted for settlement analysis.In consideration of characteristics of settlement,gray theory is introduced,which can reflect project dynamic changes.The basic theory of gray theory and the modeling process of gray theory is presented.Combining data of Luhun dam the model is established,analysis result show that the model is of high precision and can reflect the up-to-date change trends. |
| Keywords: | earth-rockfill dam settlement regression model gray theory |
