It is important to consider deformation and/or failure when design and planing of earth structures are carried out. For the purpose of this, it is thought that finite defference method is effective, which is able to represent progress failure and large deformation such as lateral flow. In this paper, the part of numerical analysis for rational de-sign is investigated. Next, characteristic of formulation of finite defference method to present progress failure and large deformation is shown. Finally, the example simulation of fileld application to represent progress failure and large deformation in recent years in shown. This example is to simulate actual accident of collapse of earth retaining. Based on above, it is thought to be important to estimate procces of deformation quantatively and to understand mechanism of effect which supports mobilize.
