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

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 anti-slide 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 deformation.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 pagoda-mountain,and compared it with the other methods.
