Based on the data obtained from the compression creep test of the argillaceous sandstone, the meshless method was introduced to study the rock creep, whose formula was derived from the generalized Kelvin model based on fractional calculus.
Specimens were derived from the unweathered and nonvibratory argillaceous sandstone collected from coal mines.
After ensuring that the macroscopic parameters of the argillaceous sandstone specimens in the physical experiments were consistent with those of the numerical simulations, the contrastive analysis of the DEM-AE model was carried out.
The cemented and argillaceous sandstone samples all have lower porosities (resp., 0.44%-1.73% and 1.2%-2.91%) and permeabilities (resp., 0.046-1.110 mD and 0.016-0.130 mD) than sandy reservoirs (resp., 1.73%%-6.49% and 0.480-5.110 mD) (Figure 5(a)).
Soft rock is one of the rock types encountered frequently in geotechnical engineering, which is less than the uniaxial compressive strength of 25 MPa, covering a series of sedimentary rocks, such as sandstone, mudstone, argillaceous sandstone, sandy mudstone, and siltstone.
The uppermost Informal member of the terrestrial Pliocene Bidahochi Formation is a tuffaceous, fluvio-lacustrine sandstone that extends from northeastern Arizona (Figure 11) (Plate 1) Into nearby parts of New Mexico in the area northeast of the Little Colorado River (Repenning and Irwin, 1954), The sediments of the Bidahochi Formation were deposited by southwestward flowing streams (Hack, 1942) and were derived from the Chuska Mountains, and the Defiance, Zuni, and Mogollon Plateaus (Klersch and Keller, 1955), The sandstone member is composed predominantly of white to very pale brown, cross-bedded, poorly cemented, medium- to fine-grained, argillaceous sandstone with a few beds of white rhyolitic ash (Repenning and Irwin, 1954), and has a maximum thickness of approximately 600 ft.
The Tanawal Formation consists of quartzite speckled quartzite quartzose sandstone argillaceous sandstone phyllite shale and quartzose conglomerate.
Soil types alternate between uniform coarse-textured soils and duplex soils (in the sense of Northcote 1979) formed by the downslope movement of coarse material over in situ clay material derived from shale or argillaceous sandstone. All soils have a well-developed biomantle.
* Argillaceous sandstone, a kaolinic red sand of variable granulometry, presenting at times a cross-section stratigraphy and an alternation with red, violet or yellow clay, and beds of conglomerate hardened kaolin gravel.
