Optimization of Pre-tensioned Anchor Cable Force for Multi-anchor Anti-sliding Piles Based on Unknown Load Method
This paper first introduces the influence matrix method determined by the cable force,based on the theory,the anchor cable-anti-slip pile anchor Midas model is established and the target cable force that satisfies the displacement constraint conditions is obtained by the unknown load method,and finally the design cable force and the landslide thrust are combined on the pile to obtain the corresponding internal force displacement.The results show that under the tensile and landslide thrust loading of the numerical design cable force,the maximum bending moment value of the multi-anchor anti-slip pile pile body is greatly reduced compared with the cantilever pile,and the displacement of the pile top can be effectively controlled to 0,and the displacement of the overall pile body can be improved.
