【摘要】 在不同类型黄土的研究基础上,通过SEM图像处理技术,提出了黄土微观结构中结构单元体大小-形态分布、孔隙特征等结构要素定量评价指标,应用计算机图像处理技术,对几种黄土在不同动荷载作用下的变形进行了分析以及对地震灾区黄土受地震破坏和未受破坏的黄土微结构形貌进行了定量处理,分析较好地解释了黄土工程地震性质.更多还原

【Abstract】 Based on the study of various kinds of loess, the quantitative assessment targets are presented,involving the unir size,the mophology and distribution,pore geatures of the microstructure of loess.Some kinds of loess deformations under different dynmic loading actions are analyzed.The topography of loess in the earthquake destroyed region and wadestroyed region is quantitatively described,giving a better explanation of the nature of engineering seismics of the Loess.更多还原
