摘要
Abstract
Through experimental researches of X-ray powder diffraction, grain-size analysis, water physical property and shear strength for clay altered-rock and fault argillaceous materials, their engineering geological characteristics are compared and analyzed. The results show that clay altered-rock mainly contains illite, kaolinite, montmorillonite clay mineral and quartz etc, followed by carbonate and feldspar, so their mineral composition, components are similar with fault argillaceous materials. The tests of grain-size and water physical property show that the clay altered-rock and fault argillaceous materials are domina-ted by gravelly clay, and the minority is clay sand, both of which have the same shear strength. Clay altered-rock can be classi-fied as cuttings mud from the aspect of structural surface character. The research provides a favorable basis for evaluation of avail-ability of clay altered-rock and classification of engineering properties.关键词
