通过静三轴试验对京沪高速铁路徐沪段有代表性的下蜀粘土填料改良进行了研究。证明用钢渣掺入路基土粘土填料中能提高路基土的强度。通过离心模型试验对改良后的路基变形情况进行了初步分析。
The static triaxial test was used to study the improvement of the silt filler in Xushu section of Beijing-Shanghai high-speed railway. It is proved that the incorporation of steel slag into subgrade clay can increase the strength of subgrade soil. Through the centrifugal model test, a preliminary analysis of the improved subgrade deformation was carried out.
