Abstract: This paper based on geological conditions, soil parameters, design parameters of counterfort retaining wall and feedback information of construction, analyzed the inclination accident of a road counterfort retaining wall located in Chongqing. According to the analysis of the result and deformation characteristics of counterfort retaining wall, analyzed the cause of counterfort retaining wall inclination. Finally, the foundation grouting reinforcement treatment and the precaution using prestressed anchorage to strengthen the stability of counterfort retaining wall is put forward.
