摘　　要：贵州省六盘水市某大型桥梁位于岩溶地区,其主墩桩基采用人工挖孔桩,施工前分析地质条件,确定了大直径人工挖孔桩护壁做法和溶洞处理措施,避免了机械钻孔桩漏浆污染地下水源,保护了饮用水资源,减小了噪声污染,可为类似工程提供借鉴。A large-scale bridge in Liupanshui City,Guizhou Province is located in a karst area.The main pier pile foundation adopts manual digging piles.The geological conditions are analyzed before construction,the wall protection method of large-diameter manual digging piles and the treatment measures for karst caves are determined to avoid the leakage of mechanical bored pile Pulp pollutes groundwater sources,protects drinking water resources,and reduces noise pollution,to provide reference for similar projects.

关 键 词：岩溶地质 人工挖孔 旋挖成孔 溶洞处理
