摘　　要：文章根据摩擦桩的荷载传递机理,对摩擦桩进行受力分析与计算,从而建立起摩擦桩单桩承载力的数学模型。该模型可用于计算机进行优化设计,并从该模型的影响因素出发,有效地选择相应的施工方法,可更好地指导施工,并就此模型对施工中出现的瓶颈桩问题和桩周土的含水量对承载力的影响问题作初步探讨。Based on the load transferring mechanism of friction piles ,mechanical analysis and calculation of friction piles are carried out,and the mathematic model of single-pile bearing capacity is established. This model can be used in computer optimizing design, and effective construction methods can be chosen considering factors analyzed in this model to direct construction. The influence of bottleneck piles and moisture content of soil around the piles on bearing capacity is discussed in this model.
