摘要
竖向抗压单桩承载力包括桩侧阻和桩端阻。本文讨论了桩侧阻分布模式的影响因素及桩端持力层对桩侧阻的强化与弱化效应,以工程应用实例说明固化桩端持力层有助于提高基桩承载力,适当选择桩端持力层,可以降低工程造价和施工难度,缩短工期,增加施工质量可靠性。
The bearing capacity of vertical compressive piles consists of skin friction and tip resistance. The influencing factors of distribution mode of skin friction, and the strengthening and weakening effect of pile tip resistance on skin friction, are discussed in this paper. Some project cases are illustrated to prove that solidification of pile tip can improve the bearing capacity of foundation piles ; properly choosing pile tip resistance can reduce the cost of project and construction difficulty, shorten the construction time and improve the reliability of construction quality.
