| 摘 要： | 预应力管桩在饱和土体中的承载力具有明显的时效性,利用圆孔扩张理论和有效应力原理得到考虑时效性的承载力计算方法,对预应力管桩承载力的影响因素进行分析指出:土层参数中内摩擦角对承载力大小影响最为显著;在同一地层条件下,固结系数对承载力增长快慢的影响很大。

| Abstract: | The pre-stress pipe-shape pile has obvious ageing to the carrying capacity of saturated soil.It obtains a calculation method of carrying capacity which has considered ageing by using the hole expansion theory and effective stress principle and analyzes affecting factors to the carrying capacity of pre-stress pipe-shape pile.It points out that the influence of angle of internal friction of soil horizon parameters is the most obvious to the size of carrying capacity and;the influence of coefficient of consolidation is great to the increase speed of carrying capacity. |
