Recently, many numerical studies have been carried out on the behavior of earthquake wall caused by excavation of the urban area to utilize the underground space, and studies on the behavior of the earthquake wall by ground excavation have been actively carried out.The stability of the ground excavation is socially important because it causes the equilibrium to collapse and the deformation of the retained wall is caused as well as it affects the adjacent structures.In the present study, in order to analyze the deformation of the retained wall and the stability of the adjacent structures caused by the excavation of the ground, the operation of the three-dimensional analysis, which completely reproduces the situation of the site, is limited by the time and economic problems. The deformation and stability of the wall are predicted and reflected in the design.It is also reported that the mechanism of ground deformation due to the deformation of the earth retaining wall during excavation is divided into the geometric shape difference of two or three dimensional excavation and the two dimensional excavation occurs more than the three dimensional excavation. Since the geometric shape is sensitive to the deformation mechanism, the behavior of the earth retaining wall related to the geometry of the excavation plane is actually three-dimensional. Therefore, the behavior of the retaining wall required for the stability of the retaining wall can be accurately predicted There will be difficulties in doing so. In order to overcome this disadvantage, finite element method is widely used to derive precise information about the behavior of the retaining wall and it is required to design a reasonable way to express the behavior of the 3-dimensional earth retaining wall due to the ground excavation.Therefore, in this study, numerical analysis and numerical analysis of two - dimensional finite element analysis of elasto - plastic marble, based on horizontal displacements of the wall and the settlement of the ground, were obtained and the following results were obtained.The displacements of the wall of the retaining wall were similar to those of the numerical analysis and field measurement, but showed similar displacements. In horizontal deformation of the wall, carbon segregation and two-dimensional finite element analysis are similar to those of three-dimensional finite element analysis, and two-and three-dimensional finite element analysis is similar to that of carbon sequestration. I could.This study is a limited case study, but the numerical analysis result and the field measurement result show a little difference. The ground condition and the soil parameter used in the design may be different from the field, and the excavation depth, It is judged that it is generated differently from the design time.Therefore, it is necessary to review various geotechnical characteristics and analytical methods based on the measured values considering design conditions in the future, and the design and measurement studies should be done together, so that more reasonable and stable design and construction should be done.
