桩锚支护在深基坑工程中的应用及有限元分析

The application and finite element analysis of the pile-anchor system in deep foundation

文章结合某基坑工程实例,运用有限元软件模拟桩锚加固的效果,并与现场实测数据进行对比,通过有限元软件模拟的结果与实际情况基本一致。得到了一些有价值的结论,要合理布置锚杆的位置,恰当选取支护桩的刚度和入土深度,在可以保证刚度条件、不增加内力的情况下,做到安全又经济的设计。

Combining with a project example.By adopting the finite element software,we simulated the process of pile-anchor reinforcement.The real data measured is generally corresponding to the result from simulation.Based on this idea,selecting suitable rigidity of the anchor and depth;it can be guaranteeing the safety and economy under a reasonable deformation and not increasing internal force.
