... Abstract Basic research on the physical properties of soft clay currently lags behind the construction of buildings and infrastructure, such as dams, on these soils. To address this issue, the present study analyzed the engineering physical characteristics, mineral composition...

... of the weakening process of rocks at great depths after interaction with water, we performed X-ray diffraction analysis, scanning electron microscopy, and mercury intrusion porosimetry experiments to investigate the mineral compositions, microstructures, and porosity characteristics of four clay-bearing...

The heterogeneous representation method...

... anchor can adapt to the deformation of the rock mass, realize rapid anchorage, and obtain larger anchoring force while continuously tensioning. In this paper, the structure composition of rock umbrella anchor is introduced at first. Secondly, based on the geometric characteristics of the structure...

... Abstract The manuscript presents initial results of a potential linkage between the mineral composition and structural strength in geological samples from a hydropower tunnel currently under construction. Changes in rock properties due to processes of both chemical as well as mechanical...

... kinds of marls indicates that the major factor in swelling of marls is their hydration. Unloading has no impact on their swelling in comparison with their mineralogical composition and the type of clay minerals. Also the results indicate that red marls are more compacted with higher resistance. Finally...

... Abstract When drilling wells through shales, the rock mechanics and physico-chemical properties of shales are critical to design the trajectory of wells, mud weight as well the mud chemical composition. In spite of their large occurrence, shales are also among the lesser known rocks...

... ABSTRACT Metamorphosed carbonate bearing rocks contain mainly calcite, dolomite and secondary minerals which are their Mohs scale hardness over five. These minerals depend on chemical compositions of rocks, pressure and temperature condition of metamorphism are developed such as diopside...

.... Formation of secondary minerals, especially clay minerals, by chemical weathering has not been identified, but the change of chemical weathering index with respect to the degree of weathering indicated that leaching of chemical composition had been occurred. Changes in physical and mechanical rock...

... composition in rocks have been studied. Further more, the failure properties characterized by the variation of fractal dimension are also studied by energy method. I. INTRODUCTION Since rocks generally arc brittle materials, the generating, propagating, and combining of cracks in rocks play an important...
