Stability and Reinforcement of Subgrade Slope of Weathered Rock Considering the Effect of Seepage

Abstract:

Taking the slope of K178+500-K178+550 of Beian-Heihe expressway as example, based on the steady saturated-unsaturated seepage theory and simplified the seepage force of groundwater into equivalent nodal load, then using the strength reduction finite element method to analysis the stability and potential slide area of roadbed slope which has no engineering measures; the interaction between slide-resistant pile and weathered rock can be reasonably considered by using the contact surface element, the result shows that, the safety factor of roadbed slope can be improved and the shearing strength of roadbed slope can be evenly dispersed by the reinforcement measure. The result can be used for the stability evaluation and reinforcement of subgrade slope of weathered rock area.
