摘　　要：通过分析高填方单排桩式桥台结构水平向承载能力病害的成因,采用气泡混凝土轻质填料换填台后宕渣,以减小台后填料水平土压力的影响,使桥台桩基开裂病害加固得到有效处置。轻质填料的使用,可减小台后的工后沉降,避免台后跳车现象的发生,改善道路行车的状况。同时,针对软土地质条件下的桥台结构设计,提出设计对策与建议,为同类型桥梁设计工作提供启示与借鉴。By analyzing the causes of the horizontal bearing capacity disease of the high fill single row pile abutment structure,the slag after the abutment is replaced with the light filler of bubble concrete,so as to reduce the influence of the horizontal earth pressure of the filler behind the abutment and effectively deal with the cracking disease and reinforcement of the abutment pile foundation.The use of light filler can reduce the post construction settlement behind the abutment,avoid the occurrence of vehicle jumping behind the abutment and improve the condition of road driving.At the same time,the design countermeasures and suggestions are put forward for the abutment structure design under the soft soil geological conditions,so as to provide enlightenment and reference for the design of similar bridges.
