Abstract
The finite element method has been a successful analytical tool in solving various geotechnical engineering problems such as prediction of settlements. Accuracy of the finite element analysis depends on that of estimation of soil properties. However, reliable soil properties cannot always be obtained easily. Hence, an extended Kalman filter, numerical technique developed in the field of system identification, is introduced. In the course of this, the finite element technique is employed in estimating spatially variable soil properties using the observed response values. Furthermore a discussion on applicability of this back analysis method is provided.
