摘要

摘要: 为了使新型的高聚物碎石桩在工程中的应用和推广,通过对3种不同高聚物密度的高聚物碎石桩模型分别进行了模型试验和有限元扩展分析,研究了其承载特性。结果表明：高聚物碎石桩的承载能力分别随着高聚物密度、桩长、桩径的增加而增加;在同一级桩顶荷载作用下,得到模型桩的桩侧摩阻力会随着高聚物密度的增加而增大;在相同高聚物密度下,得出桩径越大,桩端阻力的荷载分担比越小。另外,高聚物碎石桩的承载能力优于碎石桩和CFG桩。

Abstract: In order to apply and popularize the new type polymer gravel piles in engineering, model tests and finite element analyses are carried out on three kinds of polymer gravel piles with different polymer densities, and their bearing characteristics are studied. The results show that the bearing capacity of polymer gravel piles increases with the increase of polymer density, pile length and pile diameter. Under the same pile top load, the pile friction resistance of the model pile increases with the increase of polymer density. Under the same polymer density, it is found that the larger the pile diameter, the smaller the load sharing ratio of the pile tip resistance. In addition, the loading capacity of the polymer gravel piles is better than that of the gravel piles and CFG piles.
