In this study, We have carried out 2D & 3D numerical analysis is to find the cracking causes of fixed cantilever wall during transverse pre-stressing after construction of the reaction bed. The material properties, which are used to numerical analysis, are the results of the core specimens analysis of casting bed. And we have checked the design codes in case of the concrete core specimen strength is less than the design strength.
