摘　　要：基于室内土动力学试验、电化学试验和电镜扫描图像处理分析,研究了饱和黄土液化的机理,建立了饱和黄土孔隙水压力和应变的增长模型,定量研究了黄土液化的主要影响因素。Based on laboratory tests of soil dynamics, electric chemistry and scanning by an electronic microscope, the mechanism of loess liquefaction were studied. The mathematic models on pore pressure generation and axial strain developement were established. The key factors of influencing loess liquefaction were quantatively approached.

关 键 词：黄土液化 机理 孔压 应变 影响因素 试验
