Study on Design Method of Slope Supporting System of Anchor Cable Frame Beam and Anti-slide Pile under Deformation Compatibility Condition
At present,the deformation compatibility is not considered in the slope support system of anchor cable frame on slope surface and anti-slide pile at slope toe in design practice.There is the risk of sequential failure of two protection forms in the supporting structure.The deformation compatibility formula of anchor cable+anti-slide pile supporting system is derived through establishing the relationship between slope deformation and deformation of anchor cable and anti-slide pile.Combined with the deformation calculation method of anchor cable and anti-slide pile,the design method of anchor cable+anti-slide pile supporting system under the condition of deformation compatibility is proposed.It is proposed that the low-stiffness anchor cable should be used and the high prestressed locking value of anchor cable is set as far as possible when the sliding force cannot be accurately determined.At the same time to guarantee the anchor cable fully to play the anchorage force,its adaptability to deformation should be enhanced,and the deformation compatibility of anchor cable frame+anti-slide pile supporting system should be improved.
