摘　　要：通过野外剪切波速测试、室内动三轴试验和微结构扫描对强夯黄土地基进行了对比分析。结果表明 ,强夯有利于提高黄土地基的抗液化性能 ,但不能完全消除黄土地基的液化 。Based on field estimation of shear wave spe ed and indoor dynamic 3-ax ial test and scanning of microstructure, the rammed loss ground is analyzed. Tes t results show that ramming is beneficial to enhancing the anti-liquefaction of the loss ground but unable to eliminate its liquefaction. It can serve as refere nce to the construction work with ramming in loss region.
