摘要
大口径大吨位钻(冲)孔灌注桩的施工质量对单桩承载力的影响极大,只有用先进的设备和成孔工艺,缩短成孔时间,保证孔底清渣工作,把好砼灌注质量关,才能保证桩基的施工质量,从而保证单桩承载力。
The construction quality of major diameter driving pile roduce a great impact on load-bearing capacity of pile. In ordet to control the constrction quality of pile, it is absolutely necessary to abopt abvenced e-quipment and driving techology, short drining time, assure clearing away residue of pile bottom, control concrte grouting quality, andthen the load -bearing capacity of pile would be assured.
