摘　　要：本文对水泥改良黄土填料,在不同掺合比、不同含水量、不同压实度下进行无侧限抗压强度试验,探讨水泥改良黄土的强度特性。试验结果表明:人工压实黄土强度低,水稳定性差;采用低掺量水泥可显著改善黄土强度特性,能满足高标准铁路路基填筑要求。Unconfined compressive strength test is conducted for cement improved loess filling under different mixture ratio, different water content and different degree of compaction. Strength properties improved loess is discussed in the paper. The test results show that：artificially compacting loess has a low strength and poor water stability; low mix proportion of cement can improve the intensity characteristic of loess, and meet the high standards of railway subgrade filling requirements.
