Finite element analysis on pile anchor support deep foundation ditch

The paper makes finite numerical simulation on a deep ditch excavation in Shenzhen by using strength reduction FEM,it analyzes stability of the foundation,and relationship between deformation and combining of single pile and anti-slide pile with different anchor number supporting schemes,it discusses relationship between prestress and stability of different anchors,as well as deformation and internal force of the pile when using the pile anchor supporting,so as to make the best designing scheme of foundation slide slope.
