Seasonal changes in the fine-grained soil conditions caused by the freeze-thaw cycle of their physical and mechanical properties of the changes to the actual construction harm. Through indoor uniform orthogonal test explore and study the fine-grained soil in different water content, density, soluble salt content and clay content conditions, the different cycles of freezing and thawing, use direct...
In this paper, the author investigates root's soil mechanics' mechanism and influencing factors of a typical soil reinforcing plant- Hippophae rhamnoides Linn. in the area that has been destroyed by wind and water. This investigation has been done from two aspects: shear strength of root-soil composite and friction characteristic of root-soil interface. The results show that when the root diameter...
Through a series of direct shear tests on the interfaces between soil-soil and soil-roots of Artemisia sphaerocephala and Sabina valgaris, friction properties of the interface were examined, and the influence of normal stress, dry density of soil, water content of soil on friction properties were analyzed. The results showed that the shear relationship of interface between soil-roots of Artemisia...
In this paper, we investigate the influence on shear strength of the roots of four typical plants which can fix the soil in coal mining subsidence area by direct shear tests ,and the shear strength of the root soil composite .The results indicate that with the same root diameter (1.25 mm) , Sabina valgsris Ant., Salix psammophila, Caragannmicrophylla Lam. Artemisia sphaerocephala Krasch are more intensive...
