摘要
本文从设计角度分析了桩基承载力的主要影响因素,研究了泥皮、孔底沉渣、成孔时间、桩孔的垂直度对设计承载力的影响,并且从消除泥皮影响、处理孔底沉渣、调整作业时间及保障桩孔垂直度等方面进行了探讨。
This paper gives an analysis of main influence factors on bearing capacity of the foundation pile from design; some factors of mud cake produced in the construction process, sediment in the hole bottom, the time of pore-forming and verticality of the pile will affect design bearing capacity. This paper gives an discussion on eliminating effect of mud cake, treatment of sediment, adjusting operation time and assurance for verticality of the pile hole.
