| Abstract: | The Kalman filtering theory is applied to the back analysis of parameters of mass concrete displacement field for the first time. The time-spreading equation and the observation-correcting equation of displacement field are deduced. After the coupling problem of extending Kalman filtering theory and FEM is solved, the corresponding computing formulas are deduced and then the back analysis procedures are given. Many more useful conclusions about the back analysis based on Kalman filtering theory are tested and discussed through a classic example. |
| Keywords: | parameters of displacement field Kalman filtering theory stochastic back analysis |
