Stability analysis of a roadside slope in Xinjiang under the influence of construction disturbance

Abstract

Affected by continuous construction disturbance, the stability coefficient of a slope is calculated to be 0.95, which does not meet the requirements of slope stability; in order to prevent slope destabilization and damage, two kinds of reinforcement schemes are formulated, scheme 1 is “circular anti-slip pile + anchor + cut-off drainage”, scheme 2 is “square anti-slip pile + cut-off drainage”. Numerical analysis of the stress field, displacement field and stability coefficient changes of the two reinforcement schemes; the study shows that:1) Scheme 1 and 2 both meet the requirements for slope stabilization, improving the slope stability coefficients by 45.26% and 35.79%, respectively, relative to the pre-stabilization period; 2) The displacement and deformation of the slope corresponding to the two reinforcement schemes have decreased significantly relative to the pre-reinforcement period, i.e., the coarse reinforcement measures in the schemes have produced effective reinforcement effects; 3) Considering comprehensively, Scheme 1 has more long-term stability benefits, and Scheme 2 has more economic benefits.
