摘要
针对我国西北、华北地区广泛分布的黄土,选用新型高分子固化材料SH进行黄土化学改良,进行了SH改良黄土抗冻性试验,研究固化黄土在水和负温共同反复作用下的抵抗能力,得到了不同冻融次数条件下改良黄土的无侧限抗压强度等的变化规律。研究结论对于寒冷地区渠道和路基工程建设等有重要意义。
For the loess distributed in northwest and north of China, polymer solidified mate- rial SH was choosed for loess improvement. A study was conducted to analyze the properties un- der freeze-thaw cycles of the loess solidified by SH. The changes in unconfined compressive strength under different freeze and-thaw cycles were obtained.
