饱和黄土液化的孔隙微结构特征

STUDY ON THE LIQUEFACTION MECHANISM AND PORE MICROSTRUCTURE OF SATURATED LOESS

摘要:

通过对黄土中各类孔隙含量的定量测试及数理分析,介绍了黄土孔隙微结构的计算机图像处理分析方法,并从孔隙微结构的角度研究了饱和黄土液化机理.在此基础上,建立了孔隙微结构特征与黄土液化势的定量关系,从孔隙微结构角度对中国不同地区黄土液化势进行了评价.

Abstract:

Through quantitative tests and numerical analysis of pore contents of loess, computer-added image manipulation method of microstructure of loess pore is introduced and the mechanism of saturated loess liquefaction is studied. The quantitative relations of pore microstructure and loess liquefaction potential are established and the loess liquefaction potentials in different areas of china are estimated with pore microstructure.
