基于高速客运专线对路基变形的严格要求,路基填料改良已成为高速铁路必须解决的问题。本文通过大量的土工试验和理论分析,研究了石灰改良黄土和水泥改良黄土的强度机理、压缩特性、水稳定性、强度特性以及影响这两种改良材料工程力学特性的主要因素,并进行了对比分析,为黄土地区高速客运专线路基填料的选择和应用,提供了参考依据。
Based on the strict requirements of subgrade deformation of high-speed passenger dedicated lines, the improvement of subgrade filling has become a problem to be solved by high-speed railway. In this paper, through a large number of geotechnical tests and theoretical analysis, the paper studied the strength mechanism, compressive properties, water stability, strength characteristics and the main factors that affect the mechanical properties of loess and cement improved loess. Analysis, provide reference for the selection and application of roadbed packing for high-speed passenger line in the loess area.
