锚索抗滑桩系统内力变形研究

Research on Internal Force and Deformation of Anchor Anti-Slide Piles System

在对锚索抗滑桩系统内锚索与抗滑桩受力状态综合分析的基础上,认为锚索的拉伸变形对锚索抗滑桩系统的内力及变形存在一定影响,基于锚索与抗滑桩的变形协调原理,提出了锚索拉力及其变形的计算方法,推导了抗滑桩桩身位移和内力的计算公式,并将该方法用于工程实例分析。通过与其他方法比较,说明使用该方法计算锚索抗滑桩的合理性和经济价值,并分析了锚索变形以及拉力大小对锚索抗滑桩系统内力变形的影响,所得结果已得到后期模型试验的数据支持。

Comprehensive study on the flavor undergoing force of the anchor and anti-slide pile in the anchor antislide piles system shows that the deformation of the anchor has a close connection with the internal force and deformation of piles. According to the deformation consistence principle, a method is presented to calculate the tensile force and deformation of anchor as well as displacement and internal force of the anti-slide, and the corresponding formula is derived in detail. Compared with the other methods by an engineering example, it indicates that the calculation method has the economic value. Meanwhile, the example shows that the tensile force and deformation of the anchor has a great influence upon the internal force and deformation of the anchor antislide piles, and the calculation result is validated by the data of the later experiment.
