摘要
抗拔桩的极限抗拔力是软土地基中抗拔桩设计的重要参数,为研究和分析抗拔桩极限抗拔力的影响因素,在国内外相关研究分析的基础上,结合上海火车南站抗拔桩静载试验实测数据,并通过ABAQUS有限元软件进行数值分析,研究了桩体弹性模量、桩长、桩径3种因素对抗拔桩极限抗拔力的影响。结果表明,桩体弹性模量对抗拔桩的极限抗拔力影响不大,而桩长、桩径的增加均能明显提高抗拔桩的极限抗拔力。
Ultimate pullout capacity of uplift pile is an important design parameter of uplift Piles, and Elastic modulus, length, diameter of pile are the important influencing factors of Ultimate pullout capacity. Based on Static Load Test of uplift Piles of Shanghai South Railway Station, ABAQUS finite element is used to study the influence to ultimate pullout capacity of the three factors. The results show that elastic modulus of pile has little effect on ultimate pullout capacity, and increase of length, diameter of pile can markedly improve ultimate pullout capacity of uplift pile.
