Study on settlement deformation characteristics and foundation treatment of expressway splicing section
In order to improve the design level of the highway renovation and expansion project,relying on a certain highway project,a plane calculation model was established using finite element software ANSYS to explore the influence of parameters such as fill height,widening width,and soil compression modulus on the settlement of various monitoring points on the surface of the roadbed,as well as the trend of uneven settlement changes between new and old roadbeds;A technical and economic comparison was conducted on two foundation treatment schemes,cement mixing pile and compacted gravel pile.The research results showed that the uneven settlement of the road-bed in the highway splicing section increases with the increase of filling height and widening width,and decreases with the increase of soil compression modulus.Moreover,the cost-effectiveness of cement mixing pile treatment for foundation is better.
