【摘要】 从土力学途径出发,在三轴试验的基础上,提出了反映重塑黄土和原状饱和黄土结构性的定量化参数。开展了对重塑、原状饱和黄土的结构性定量化研究。对重塑、原状饱和及重塑饱和黄土进行了大量常规三轴试验。较为详细地研究了重塑黄土和原状饱和黄土的结构性变化特征,论证了所建议的重塑黄土及原状饱和黄土的结构性参数具有很好的适用性。完善了黄土结构性定量化参数。更多还原

【Abstract】 By the soil mechanical method,grounded on the results of triaxial compression tests,a quantitative parameter of structural properties,which can reflect structural property of the disturbed loess and saturated intact loess,has been proposed.Then,a study of structural properties of disturbed loess,saturated intact loess has been carried out primarily.A large number of routine triaxial tests are carried out on the unsaturated soil triaxial apparatus for different water content of disturbed loess,saturated intact loess and saturated disturbed loess.The variation regularity of disturbed loess and saturated intact loess has been studied minutely,and the applicability of the new structural parameter has been confirmed.These works will improve the quantitative parameter of structural properties of loess.更多还原
