摘要
结合具体工程,采用三维有限元分析方法,对地面堆载作用下邻近桩基变形性状进行了模拟分析。分别研究了浅层土体弹性模量和桩身刚度对各排桩基侧向变形的影响,并将有限元计算结果与实测数据进行了比较。分析结果表明,浅层土体的弹性模量对被动桩基的变形影响更显著;被动桩能有效地控制堆载作用下邻近土体的变形,从而对附近建筑基础起到保护作用。分析结果能为类似工程的设计提供指导。
The 3D numerical analysis of pile influenced by lateral soil movement due to surcharge loads in a project is presented.Analytical results show that piles’ deformation can be affected by elastic modulus of soil in superficial layer and piles,especially the former.The calculated results are identical with the monitored data,and lateral soil displacement can be reduced by the piles,so the nearby foundation can be protected.These results would be helpful to the design of engineering practices.
