巴东组软岩残积红色黏土物性特征
Petrophysical Characteristics of Residual Red Clay in Badong Group Soft Rock
摘要
Abstract
In the whole process of laterization, red clay shows some mechanical properties such as high liquid limit, high moisture content, high plasticity, dispersion, and other special physical mechanical properties through the accumulation of iron and aluminum minerals and leaching of base composition. The physical and mechanical properties of the red clay are carried out in different depths, elevation points and weathering degree of the Three Gorges Reservoir area by the X-diffraction experiment, complete chemical analysis, environmental scanning electronic microscope and other means of micro-test. The red clay is analyzed the phase structure and Badong Formation of residual red clay slope deposits of macroscopic and microscopic physical properties and laws are approached. The results show that the red clay's physical and mechanical properties along the horizontal and the depth direction have its regularity, the style of bed rocks, weathering degree, mineral composition and structure and grain size characteristics are the main factors of this law.关键词
