【Abstract】 This paper summarizes the fundamental principles of development of hybrid models of displacement for concrete dams by mathematic statistics method, and expands the temperature component and time effect component. A slotted gravity dam is taken as an example to introduce the procedure of the establishment of a hybrid model in detail. It has been proved that the fitting between the results of the hybrid model and the values observed in situ is accurate, and the forecasting of the displacement is reliable.更多还原
