“…This is consistent with the conslusions in this paper. Furthermore, Q,J.Xu et al also obtain the same conclusion in the study on biotechnical means of soil stabilization using willow cuttings [20] . As to the root-soil interface's characteristics of Hippophae rhamnoides Linn., friction coefficient of root-soil interface is 3% higher than that of soil-soil interface, which accords with the conclusions that Hui-wen Xing(2009) [18] obtained in his previous research for the fiction characteristics of the four plants' root-soil interface.…”

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 is less than 1.5m, both the shear strength and cohesion force of Hippophae rhamnoides Linn.in root-soil composite are stronger than those of in pure soil, and the friction force of root-soil interface is more intensive than soil-soil interface. Shear strength of root-soil composite is enhanced by its cohesion force and root-soil composite's friction. At different moisture conditions, both the shear strength and cohesion force of root-soil composite show an increase first, then a decrease, and both of them reach the maximum at 14.8% water content. The friction coefficient of root-soil interface reduces as the moisture increases; whereas, shear strength and cohesion force of root-soil composite and friction coefficient of root-soil interface increase as dry density increases.

This paper presents the study of a landslide induced by rainfall above a railway line in terms of site investigations, laboratory tests, finite element, and limit equilibrium analyses. The purpose of the study is to identify the cause and failure mechanism so as to prevent the recurrence of such failure. The slope concerned was composed of 3∼4 m thick fissured clay overlying highly weathered mica marble interbedded with quartz schist. The slope was cut into two steps and was protected by a masonry revetment and a thin masonry retaining wall at the toe. The region concerned suffered a whole month's light drizzle in September, after which a rainfall of an intensity of 80 mm (in 48 h) occurred 5 days prior to the failure that happened on October 5, 2004. The rainfall infiltration and a failed drainage system behind the retaining wall resulted in high saturation of the clay and finally led to an undrained failure. The short-term slope stability using total stress parameters was examined by the finite element and limit equilibrium analyses. The factors of safety of the slope obtained by the finite element and limit equilibrium analysis were 0.935 and 0.854, which are in agreement with the occurrence of failure. Since the slide took place through the interface of the soil and rock, the exposure of rock has significant effect on the stability.

“…Therefore, hydrogen and oxygen isotopes are useful tracers in water cycle research. it plays an important role in the study of the transformation process of water bodies, such as atmospheric precipitation, soil water, plant water, groundwater and river water [4][5][6][7][8][9]. The methods for estimating quantitatively the replenishment sources of different water bodies by using hydrogen-oxygen isotopes include mainly two or three-compartment linear mixing models [10], such as isoSource mixing model [11], Bayesian-based MixSiR, SiAR and MixSiAR mixing models [12][13][14].…”

in order to explore the characteristics of hydrogen-oxygen isotopes and ecological hydrological processes in different water bodies in the subalpine zone of Qilian Mountains, China, precipitation, soil water, plant water, groundwater and river water samples were collected from the subalpine of the Eastern of Qilian Mountains section from July to August in 2015. Qualitative analysis was used in hydrogen and oxygen isotope characteristics of different water bodies. Then, the mixing model of MixSiAR based on Bayesian theory was used to quantify the water absorption depth of shrub plant and the proportion of water source replenishment between different water bodies. The purpose is to illustrate the water migration relationship between water bodies, thereby to clarify the ecological hydrological process in the subalpine shrub area of Eastern Qilian Mountains. Results indicate that: (1) The isotopic values of various water bodies in the study area are affected by changes in the amount of precipitation, but precipitation has a smaller impact on river water. (2) Soil water of 0~20 cm is affected easily by precipitation and evaporation, while soil water of 60~80 cm is affected strongly by groundwater. (3) The water content of shrub plant in study area is mainly derived from precipitation and soil water under 0~20 cm. (4) Although the direct influence on the values of δ 18 O in groundwater and river water by precipitation is not obvious and their variation ranges are small, there are different degrees of response to precipitation, and river water responds faster to precipitation than groundwater.
