Abstract
To develop a comprehensive analysis method for highway slopes from reconnaissance to construction,this study is based on engineering practice.First,from the perspective of reconnaissance,slope stability and construction safety risks are discussed.Second,slope prevention and control measures are screened,optimized,and designed through computational calculations.Finally,combined with deformation monitoring results after slope treatment,the rationality of these measures is analyzed through deformation prediction and other methods.The results indicate that the slope exhibits significant deformation characteristics.Under rainstorm conditions,the stability coefficient of the b-b'cross-section is 0.981,indicating an unstable state;thus,the slope is highly susceptible to instability under adverse conditions.Additionally,the safety risk assessment score for slope construction is 360 points,corresponding to Risk Level Ⅰ,indicating substantial construction risks.Through optimization and screening,the single-anchor pile-slab anti-slide structure is found to be more economical.Analysis of post-treatment deformation monitoring results shows that although subsequent deformation increases,the rate is minimal,with an overall trend toward stability.The maximum predicted deformation is only 12.42 mm,fully meeting design requirements,thereby validating the effectiveness of this prevention and control measure and providing a reference for similar projects.关键词
