摘要
通过对掺石灰、掺水泥以及水泥和粉煤灰联合三种改良方法的现场试验研究分析,并进行CBR检测试验,结果表明采用水泥和粉煤灰联合法改良高液限黏土作为路基填筑材料是一种较为经济有效的改良方法。
In order to seek a method improved the high limit liquid soil into roadbed stuffing, the improved soil of calcareousness and the im proved soil of cement and the improved soil cement-fly ash are use in the fielding tests. By the CBR test, the improved method are investigat ed, the results indicates that the improved soil of cement-fly ash is a economical effect method to improve the high limit liquid soil.
