基于高速铁路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。通过大量的土工试验和理论分析,研究了石灰改良黄土的强度机理、压缩特性、水稳定性、强度特性以及影响改良土工程特性的主要因素。
Based on the strict requirements of high-speed railway on the deformation of subgrade, the improvement of subgrade filling has become a problem to be solved by high-speed railway. Through a lot of geotechnical test and theoretical analysis, the paper studied the strength mechanism, compressive property, water stability and strength characteristics of lime-improved loess and the main factors that affect the engineering properties of improved soil.
