摘　　要：通过贵州仁赤高速公路桐梓河大桥桥台施工图设计实例,阐述了公路高填方路堤桥台桩基础产生负摩阻力的原因和计算方法,提出了高填方路堤桥台施工过程、施工工艺及关键技术要点,实践结果,工程质量良好。Through the design case of construction drawing for the Zihe Bridge abutment at Renhuai-Chishui Highway in Guizhou, the reason of pile foundation of abutment at high 1ill embankment causing negauve friction and the calculating method thereof are described and then the construction process, technology and key points for such abutment are proposed. The practical result shows that the engineering quality is good.
