AM桩孔壁稳定性影响因素分析

结合现有研究成果，系统分析了AM桩孔壁稳定性的影响因素，包括泥浆重度、粘度、含砂率、钻孔深度及成孔时间等，着重研究了成孔时间对孔壁稳定性的影响，得出成孔时间越长，对孔壁稳定性越不利的结论，对今后AM桩施工有一定的指导意义。

On analysis of influential factors on stability of wall of board of AM pile

Combining with current research results, the paper analyzes the influential factors of the stability of the wall of board of AM pile, including slurry density, the viscosity, the sediment charge, the drilling depth and the time of pore-forming, mainly researches the influence of the pore time on the stability of the wall of board, and concludes the longer the pore-forming lasts, the less favorable to the stability of the wall of the board, so it is significant to direct the future AM pile construction.
