摘　　要：以某建成运营通车的城市桥梁为案例,阐述了城市桥梁超高填方桥台结构、锥坡防护、台后回填处理等设计方案和技术要点,并结合施工及运营期监测情况,总结分析了超高填方桥台设计及施工的关键技术问题。实践证明:在地形地势及地质等外部条件可行的情况下,通过合理设置桥台结构、加强锥坡设计、严控施工质量,超高填方桥台的强度、稳定性和沉降量均可控制在合理范围,能够节省建设用地和工程投资。这为类似工程提供参考经验。Taking a built urban bridge under operation as a case,the technical schemes and technical essentials of the ultrahigh fill abutment structure,conical slope protection and backfilling treatment of urban bridge are set forth.Combined with the monitoring situation during construction and operation,the key technical issues in the design and construction of the ultrahigh fill abutment are summarized and analyzed.It has been proven that the strength,stability and settlement of ultrahigh fill abutments can be controlled within a reasonable range by reasonably setting up the abutment structure,strengthening the conical slope design and strictly controlling the construction quality when the external conditions such as terrain,topography and geology are feasible,which can save the construction land and engineering investment,and provide the reference experience for similar projects.
