Simplified calculation method and stability analysis of top beam cooperative pile–anchor supporting slope structure

Aiming at the problem of insufficient research on action mechanism and stability calculation method top beam in pile-anchor support structure, firstly force deformation model are established based elastic fulcrum coordination principle structure pile anchor end this paper. Secondly, under synergy crown simplified internal force, displacement overall slope constructed. Finally, combined with an engineering example, a MATLAB program was compiled for calculation, structures crowned beams without were simulated calculated by finite element software PLAXIS 3D Geo Studio. These three aspects compared verified. The results show that minimum safety factor paper basically consistent numerical simulation condition; existence effectively enhances bearing capacity body, also restricts development; makes increase significantly improves slope. can provide certain reference value theoretical design supported considering practice.
