A finite difference software(FLAC 3D) was used to carry on numerical simulation of reinforced retaining wall which had engineering observed data.

The author introduces the constructing technique of reinforced retaining wall,compares its economic benefits with the traditional rolled earth fill dam construction method,and put forward some notices in the construction of reinforced retaining wall.

Research actuality and prospect of reinforced soil retaining wall;

Application of reinforced soil retaining wall in municipal highways

The potential failure surface of the reinforced soil retaining wall(RSRW) is the connection line of the points where layers of reinforcement have the maximal pull,its rational addressing is the pivotal problem for structural calculation of RSRW.
