520 _aIn this study, a model which could well represent the acting load on shield with crease mechanism. The acting loads on shield in model, it was considered as a large load cell. The forces on cutter face and that on skin plate are significant in this model. Force on cutter face was calculated by considering the earth pressure acting normal to cutter face, the ea1th pressme on circumference of the cutter face and the force due to weight of mud or slurry in chamber. Force due to the earth pressure on the skin plate is obtained by considering the displacements of ground in normal direction around the skin plate. This model was used to estimate the ground properties by using reverse analysis method, ground properties were obtained by applying non-linear least square method to the equilibrium conditions of forces and moments. In order to take solution of these analytical scheme was implemented in computer program which is written FORTRAN 77. Validity of the model, comparison can be made with some of the available value in previous study. Data used in the reverse analysis was carried out in Y okohoma city, Japan by using the EPBS shield with crease mechanism.
