摘要
由于土体固结存在时间效应,桩基负摩阻力也存在明显的时间效应,以昆明地区某工地桩基为例建立有限元模型,设置平行工况进行了顶荷载对固结阶段桩身摩阻力发展影响的研究。
Due to the time effect of soil consolidation,the negative skin friction of pile foundation also has obvious time effect.Taking the pile foundation of a construction site in Kunming as an example to establish a finite element model,and setting up parallel experiments to study the influence of top load on the development of pile body friction during consolidation stage.
