Stability Analysis of Pile-anchor Support Structure in High Slope Treatment
In this paper,the relationship between pile bending moment,pile shear force,pile axial force,pile horizontal displacement and pile buried depth of pile-anchor support structure is simulated and analyzed by numerical simulation method.The results show that there is a shal-low slip surface and a connected plastic zone on the upper slope of the pile top,the maximum displacement of the slope is located in the middle and lower part of the slope,the maximum settlement is 31.5 mm,the maximum horizontal displacement is 13.2 mm,and the safety factor of slope stability is1.8,which meets the requirements of GB50330-2013"Technical Code for Construction Slope Engineering".That is,the slope project is in a stable state.With the increase of pile body,the bending moment,axial force,shear force and horizontal displacement of pile body increase first and then decrease,and the maximum bending moment of pile body is 1 300 kN·m.The maximum axial force of pile row is 3 460 kN;The largest pile row shear is 410 kN;The horizontal displacement of the largest row pile is 3.15 mm.
