Research on the mechanical properties of drilling slag solidification for highway bridge pile foundations and its application in roadbed filling
Based on specific engineering projects,this article uses indoor experiments to analyze the mechanical properties of drilling slag soil,conducts microscopic research on drilling slag soil based on SEM,establishes a three-dimensional mechanical model of drilling slag solidification roadbed,and studies the mechanical properties of drilling slag soil solidification and the deformation law of roadbed filling.The results indicate that compared to the original state,the settlement generated by solidified drilling slag soil on the original surface of the highway subgrade filling project can be reduced by 19.19%,and the horizontal displacement of the subgrade can be reduced by 23.36%.Solidified drilling slag soil has high strength and low moisture content,which can meet the requirements of road performance and improve engineering quality while reducing construction costs,and has significant economic benefits.
