摘要
为了研究桩体垂直度的变化对桩、土荷载承担比、路基稳定性安全系数的影响,以工程实例为背景,采用有限元数值模拟方法,从桩土荷载承担比、桩体抗倾覆和受弯安全性以及桩间土承载等方面,研究不同垂直度桩体对路基稳定性的影响.分析结果表明,偏桩角度小于5°时,对路基稳定性的影响基本可以忽略不计.
This paper aims to examine the impacts of changes in pile verticality on piles, pile-soil load sharing ratio, andsafety factor of roadbed stability. Thus, finite element numerical simulation metliod is used to analyze some actual projects, in terms of pile-soil load sharing ratio, piles’ anti-overturning, bending safety, and bearing capacity of soils between piles. The results of the analysis show that the influences on the stability of roadbed can be neglected if the angleof the pile is less than 5°.
