条形承台梁下单排管桩偏位时承台梁的配筋设计探讨

Study of Strip Capping Beam with Off-Position Single Row Concrete Tubular Pile

对条形承台梁下单排管桩分别发生纵向偏位和横向偏位时承台梁的内力和配筋进行了研究,指出应严格控制桩的横向偏位,即使偏位值在规范允许范围内,也可能存在不安全因素,需要复核承台梁的配筋。

The internal force capping beam with off-position and steel distribution are investigated for the concrete tubular pile under strip in longitudinal and transversal direction. The results show that the off-position in transversal direction must be restricted extremely compared to that in longitudinal direction. Even within the permitted transversal off-position for concrete tubular pile, there still exists unsafely problem for the strip capping beam. It is further concluded that the steel distribution must be double-checked for capping beam.
