A soft rock fracture zone is an important element for rock slope or earth retaining, however stability studies of earth retaining wall have been lack. Therefore, this study is analyzed for a behavior of earth retaining wall with condition of fracture zone or no fracture zone and then a numerical analysis (Finite Element Method) was performed considering interaction with field monitoring data between ground and structures. As a result, applied horizontal displacement on retaining wall is correspond between result of numerical analysis and field monitoring data and displacement point stress distribution with fracture zone condition analyzed to be stable side but no fracture zone condition is expressed to be unstable side. The results of this study is purpose for applying safety construction as a top priority at field when designing for future.
