摘　　要：对于钻孔桩施工 ,正确选定成孔工艺和合理安排施工进度及工艺流程是钻孔桩施工成败的关键。对于地下水位较高兼具流砂层地质情况的断桩处理 ,采用深井潜水泵井点降水的方法是较为实用的。s In the pile-drilled construction,it is critical to select proper pile-made technology and to arrange resonable construction process and technology process,It's inavoidable that piles are fractured in construction.For the geologic conditions with high-level urderground water and liquid sand layers,it's practical to use deep-well pump to decrease water level to treat fractured piles.
