Popis:	This is a report on a study of parameters estimation, such as lateral pressure acting on retaining wall and elastic constants of soil, etc, from measured data of the wall displacement (degree of rotation) during excavation. EK-WGI method which was developed based on the extended Kalman filter of controll theory was applied to the parameters estimation method. A feature of this method can be estimated recursively unknown parameters in the direction of the depth of retaining wall. In the analysis, simulated data which were used for verification of formulation to EK-WGI method was applied. From numerical results, it was clearly observed that this method was effective to estimate these parameters.
