分析了复合固化剂加固土的强度形成机理；对素黄土、石灰加固土和复合加固土进行了击实试验、无侧限抗压强度试验、CBR试验、渗透性试验和湿陷性试验；对复合加固剂加固黄土的工程性质进行试验研究。结果表明：复合固化黄土的密度、无侧限抗压强度、水稳定性、渗透性等方面的性能都有大幅度提高；添加固化剂后的黄土湿陷性有所变小，但比起重塑作用效果甚微。

The paper analyzes the mechanism of strength forming in reinforcing soil by a new compound solidified agent and carries out tests of compaction, unconfined compression strength, CBR, osmosis and collapsibility on loess without reinforcement, loess reinforced with lime and compound solidified agent respectively; thus the engineering performance of loess reinforced by new compound solidified agent is studied. The results show that the density, unconfined compression strength, water stability and osmosis of reinforced loess are improved greatly; and the collapsibility decrease a little but is far less than the effect of re-plasticity.
