Slope Stability Remediation Using Anti-Slide Caissons
The strength reduction method is used to establish a three-dimensional finite element model of the slope stability im-provement by using anti-slip caisson.The bending moment,the shear force and the factor of safety of caissons under different design parameters are evaluated by changing the caisson location,the length and the spacing.Throughout the study of the force and the displacement of the caisson shaft under various circumstances,it is concluded that when the caisson length is short,it is in the middle and lower part of the slope,and when the caisson length is long,it is most beneficial to the stability of the slope to be set in the middle area.When the caisson is at both ends of the slope,the caisson length has little effect on the factor of safety.Finally,for a large number of mitigation plan,the optimal design of the slope stability support is determined,which can provide a good reference value for similar projects in the area.
