锚索抗滑桩与岩土体相互作用研究

Study of the interaction among anti-slide pile,anchor and soil body

就目前锚索抗滑桩的研究现状来看,基本上都是将锚索和抗滑桩分开计算,忽略了锚索与抗滑桩之间存在的相互作用关系。针对这一问题,对锚索-抗滑桩-岩土体相互作用系统的计算方法进行了研究。提出了在锚索抗滑桩设计计算中,除了应考虑锚索的强度外,还应该考虑锚索的伸长量,使其与桩的变形相协调。在此基础上,建立了新的锚索抗滑桩计算理论。本文用该方法进行了工程实例分析,并与其他计算方法所得结果进行了对比。

The present research of the anchored anti-slide pile is based on separate calculating of anchor and anti-slide pile, ignoring their interaction. In accordance with this problem, the calculation method of the interaction system among anti-slide pile, pre-stressed anchor and soil is studied. The calculation methods of the anchored antislide pile are proposed： besides considering the strength of anchor, the deformation of anchor should be considered which is compatible with the anti-slide pile＇s defomlation. A theoretical calculation formula of internal force on anchor anti-slide piles is put forward. At last, we presented the application of this method in studying and calculating the anchor anti-slide piles of the controlling scheme of the No. 1 landslide in the Yan＇an pagodamountain, and compared it with the other methods.
