| 摘 要： | 粉煤灰在高速公路工程中得到了广泛的推广应用。关于粉煤灰路基,国内重视其岩土工程性质的研究,但对于粉煤灰中污染物溶出对环境的影响问题重视不足。介绍了各国固体废弃物浸出毒性试验方法,分析了粉煤灰的浸出毒性及国外粉煤灰路基中污染物的浸出危险性实例,以此为基础就我国粉煤灰路基设计中预防地下水污染提出了建议措施。

| Abstract: | Fly ash has been widely used as backfill material in highway subgrade in China,where geotechnical other than environmental aspects are focused.The leaching toxicity test methods in some countries are introduced and the environmental risk from fly ash used in highway subgrade is analyzed.Some suggestions against groundwater pollution due to fly ash backfilled in highway are proposed. |
