In this study, detailed design requirements for segmental retaining wall (SRW) which were concerned with external stability, internal stability, and local stability were investigated and a computer program for designing the SRW was developed as well. There are little differences in the estimation of the external stability between the algorithm of the developed program and the conventional method for the design of the SRW. Methods for accounting tension failure and pullout of the reinforcement

... re incorporated in the developed program, which were essentials in the internal stability. Methods for accounting the connection strength between a reinforcement and a facing block and for accounting the bulging concerned with the shear strength of the interface between two blocks were also incorporated in the developed program, which are essentials in the local stability. Design example run by the developed program is presented in order to enhance the knowledge of the developed program.
