heavy metal-contaminated soil, ex-situ stabilization, stabilizer, backfill and macro-encapsulate

Yantu gongcheng xuebao, 2022
To improve the hydraulic characteristics of the fiber-reinforced loess, maintain the long-term stability of the loess slope, and promote the full play of the vegetation protection, the guar gum is used to cure the fiber-reinforced loess.

Quantitative Reinforcement Analysis of Loess Slope with Anisotropy [PDF]

Advances in Civil Engineering, 2019
The loess slope in east Gansu presents a large degree of anisotropy which should be considered both in the slope stability analysis and in the reinforcement design. To investigate the mechanical anisotropy presented in the loess soil, the undisturbed loess specimens are taken from the field with different sampling directions (α, defined as the angle ...

Development characteristics and genetic mechanism analysis of rainfall-induced loess flowslides in the Dongzhiyuan area

Zhongguo dizhi zaihai yu fangzhi xuebao
Under extreme rainfall conditions, loess flowslide is widely developed in the loess plateau. Loess flowslides refer to a type of geohazard involving a combination of “flow” and “slide” movements occurring in the unsaturated surface loess on slopes. These

Methane Production and Consumption in Loess Soil at Different Slope Position [PDF]

The Scientific World Journal, 2012
Methane (CH4) production and consumption and soil respiration in loess soils collected from summit (Top), back slope (Middle), and slope bottom (Bottom) positions were assessed in laboratory incubations. The CH4production potential was determined under conditions which can occur in the field (relatively short-term flooding periods with initially ...

Influence of resolution on elevation and slope at watershed scale in Loess Plateau [PDF]

SpringerPlus, 2013
Abstract This article studied the effects of resolution on elevation and slope using Statistical and Geostatistical methods. Xian' Nan watershed in Loess Plateau was taking as the study area. The base data was a 1:10000 topographic map and the resolutions studied in this paper included 5 m, 25 m and 50 m.

Analysis on Deformation Failure and Structural Mechanical Characteristics of Multistage Loess Slope Supported by Frame Structure with Anchors

Advances in Civil Engineering, 2022
Frame anchor supporting structure is widely accepted in the loess area, especially in the multistage slopes along the road. However, the development between theory and practice is not synchronous, and there exist experience and uncertainty in the design ...
