Abstract: Using the finite element strength double reduction method, a slope engineering at Bidu Expressway was taken as an example to establish a numerical analysis model. The displacement of the slope engineering and the extension of the plastic zone were calculated and analyzed. The calculation results showed that the original slope was The stability factor is 1.07. Based on this, two solutions for slope reduction and ｌｏａｄ reduc-tion and anchor reinforcement are proposed. The calculation results show that the slope stability coefficients of the reinforcement schemes of the two schemes are 1.27 and 1.36, respectively. This scheme satisfies the project. Claim.
