摘　　要：对桥台台背路基的特点进行分析,探讨桥台路基的常见病害,如桥头跳车,桥台产生水平位移、弯曲、开裂等病害,并分析其原因,提出优选适宜填料、优化碾压顺序、严格控制回填压实工艺、合理设置桥头搭板等桥台路基处理关键技术措施。This paper analyzes the characteristics ofthe subgrade on the back ofthe abutment,discusses the common diseases ofthe abutment subgrade,such as the jump of the abutment head,the horizontal displacement,bending and cracking of the abutment,and analyzes the causes,and puts forward the key technical measures for the treatment ofthe abutment subgrade,such as selecting the appropriate filler,optimizing the rolling sequence,strictly controlling the backfilling compaction process,and rationally setting the abutment plate.
