Experimental Study of Mechanical Performance of Cement-Improved Loess
-
摘要: 通过大量土工试验和理论分析,研究了水泥改良黄土的击实特性、压缩特性、强度特性以及影响因素,在列车重复荷载作用下的动力特性,论证了水泥改良黄土作为高速铁路路基基床底层填料的可行性。Abstract: Through many soil laboratory and theory analysis, compaction characteristics, compressibility, intensity mechanism and some major factors and the dynamic performace of cement improved loess under repeated load of train are discussed. It can be concluded that the performance of cement-improvde loess meets the design demand of rapid transit railway subgrade.
