摘　　要：以兰州车辆整备场路基的加固工程为例 ,详细评价了化学灌浆法的加固效果及其抗液化性状 ,进行了标准贯入试验和室内动三轴试验。试验结果表明 ,化学灌浆不仅提高了黄土地基的承载能力 ,而且增强了抗液化能力及抗变形能力。Based on the engineering practice of loess ground improvement in Lanzhou railway vehicle factory, the enhancement effect and anti-liquefaction behavior of chemical grouting are evaluated in detail. Further,the standard grouting experiment and the indoor dynamic triaxial experiment have been conducted. The test shows that the chemical grouting not only increases the bearing capacity of the loess ground, but also strengthens capacity of anti-liquefaction and anti-deformation.
