导致钢管桩基础屈曲变形的原因浅析

Cause Analysis of Buckling Deformation of Steel Pipe Pile Foundation

针对目前采用较多的带法兰钢管桩基础,现有的施工办法上存在较多的不足之处,导致钢管桩基础屈曲变形。文中借引某线路工程实例,对造成带法兰的钢管桩基础产生变形破坏的可能原因,利用有限元软件对桩体进行模拟分析,并得出建议性结论。

In view of the current use of the large flange steel pipe pile foundation,there are many deficiencies in the existing construction method,resulting the deformation of steel pipe pile foundation.In this paper,the possible causes of deformation and failure of the steel pipe pile foundation with flange are brought out by the example of a line project,and the pile body is simulated and analyzed by using the finite element software.
