Abstract: One of the hazards of the fabricated retaining wall is characterized by the tilting and the deformation of wall and the separation as well as the cracking at connections. For the hazard of this type of retaining wall, it can be mitigated by repairing the connection between the wall and the foundation. The potential causes of the tilting of a riverside prefabricated retaining wall are evaluated. The possible inner causes are the small stiffness of the retaining wall and the large areas of the backfill behind the wall. Whereas. the probable external causes are the rainwater infiltration into the backfill behind the wall. Based on the deformation characteristics of the prefabricated retaining wall, and the principle of maintaining the original appearance, economy and safety are considered to mitigate and reinforce the retaining wall. After the tilting correction and the reinforcement, the after construction monitoring data shows that the retaining wall has no deformation in the rainy season and winter.
