Interval Back Analysis on Mechanical Parameter of Geotechnical Engineering

Abstract:

The measured data and mechanical parameters were considered unknown but bounded property and interval numbers were used to denote the measured data and mechanical parameters. The interval parameter perturbation method was presented to solve interval FEM and the interval inverse analysis model was established. Based on the interval parameter perturbation method, the mean and deviation of the mechanical parameters were obtained by the back analysis. For the example of the mechanical parameter back analysis of rock mass cave in the large hydro-electric power station, the effect on the measured data precision was studied. From the results it can be found that the method is reasonable and feasible.
