摘要:
为深入研究软土地区深基坑工程中,地基加固对双排桩支护结构变形性状的影响,采用有限元方法系统分析了地基加固位置、加固深度、加固强度对双排桩变形的影响。结果表明:加固双排桩前侧、中间、后侧土体均可减小双排桩的侧向变形,其中加固前排桩前侧土体对桩身变形的削减效果最为显著; 增加地基加固深度可进一步减小桩身的侧向位移,但存在一定极限值; 双排桩前侧土体的弹性模量对双排桩变形的影响相对较大。
Abstract:
In order to deeply study the influence of foundation reinforcement on the deformation behavior of double-row pile supporting structure in deep foundation pit engineering in soft soil area, the influence of the location, depth and strength of foundation reinforcement on the deformation of double-row pile was systematically analyzed by finite element method.The results showed that the lateral deformation of the double-row pile could be reduced by reinforcing the soil on the front side, the middle and the back side of the double-row pile, and the soil on the front side of the pile before reinforcement was most effective in reducing the deformation.Increasing the depth of foundation reinforcement could further reduce the lateral displacement of the pile body, but there was a certain limit value.The elastic modulus of the soil on the front side of the double-row pile had a relatively large influence on the deformation of the double-row pile.
