摘要
在排桩支护结构中,桩顶的钢筋混凝土冠梁由于其空间效应,对支护桩的变形和内力有着不同程度的影响。在取一个排桩剖面按平面问题进行计算时,可以将冠梁的影响近似为作用在桩顶的支座弹簧来考虑,通过分析冠梁在排桩支护中的作用程度,针对不同的支护情况,提出了冠梁影响刚度的简化计算方法,可供设计人员参考。
Because of its spatial effect, the influence offing beam on the behavior of retaining piles may be significant. When the retaining pile is analyzed with a planar model, the influence offing beam can be simulated as a spring support. Simplified calculation method of the stiffness of spring support is presented based on the analysis of spatial effect offing beam.
