摘要
主要介绍了加固湿陷性黄土路基的一项新技术——冲击压实法。通过常规土工试验及显微结构试验:扫描电镜、压汞分析,并从宏观至微观,定性定量分析了加固效果,同时探讨了冲击压实法的加固机理,并提出合理的施工工艺参数,为进一步在黄土地区推广该项新技术提供了理论依据和实践经验。
A new technology,impact compaction technology in improving collapsible loess roadbed,is studied. The effects of the improvement are analyzed qualitatively and quantitatively,both in macroscale and microscale, through routine soil tests and microstructure testing methods such as scanning electron microscope and mercury intrusion porosimetry. The improvement mechanism of the technology is discussed and reasonable parameters for roadbed construction process are put forward as to provide theoretical basis as well as practical experience for the promotion of this new technology in the loess regions.
