Abstract
This study takes the Wumupu high slope support of the Biwei Expressway in Guizhou Province as the engineering background,and uses the large-scale finite difference software FLAC3D for numerical simulation to analyze the stress mechanism and working performance of the support structure at each stage.The study shows that before installing the anchor cable,the safety factor is 1.06.After 1 400 kN and 1 500 kN anchor cables had been installed,the safety factor increased to 1.11.After all anchor cables had been installed,the safety factor increased to 1.29.Under the anchoring effect of the anchor cables,the sliding trend of the slope decreased,and the horizontal and vertical displacement of the slope significantly decreased.The adaptive anchor cable after graded slope support had a good anchoring effect,and the slope was basically stable.This verified the applicability and feasibility of the adaptive anchor cable graded support method in the Wumupu high slope,which provides a theoretical basis and numerical reference for accurately determining the true stress state of slopes.关键词
