摘　　要：云南三清高速公路(曲靖段)二标段施工中,针对边坡防护桩基处于饮用水库内,地质情况复杂,地面高差大无法使用大型机械等施工难点,采用人工挖孔桩,通过筑岛围堰、井点降水和使用水磨钻等工艺,顺利地完成了施工任务。During the construction of the second bid section of the Yunnan Sanqing Expressway(Qujing Section),the slope protection pile foundation is located in the drinking water reservoir,the geological conditions are complex,the ground height difference is large,and the large machinery cannot be used.The construction tasks were successfully completed by the techniques of island building cofferdam,well point dewatering and the use of water mill drills.

关 键 词：饮用水库 桩基 筑岛围堰 井点降水 水磨钻
