Field Soil Suction Profiles for Expansive Soil [PDF]

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2021
AbstractSoil suction–based analyses are paramount to proper design of foundations in expansive soils, yet availability of field soil suction profiles from direct measurement is limited.

Physical and Mechanical Characteristics of Shallow Expansive Soil due to Freeze-Thaw Effect with Water Supplement

open access: yesAdvances in Civil Engineering, 2021
Shear strength of shallow expansive soil varies along with the depth under the freeze-thaw effect. This work investigates shear strength characteristics of shallow expansive soil by simulating the actual freeze boundary conditions of seasonal frozen ...

Stability analysis of expansive soil slopes considering shear strength decay characteristics

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2022
In order to address the problem that the dynamic decay of shear strength of expansive soil in the process of rainfall infiltration cannot be considered in the traditional slope stability analysis of expansive soil, indoor direct shear test was carried ...

Influence of Swelling on Shear Strength of Expansive Soil and Slope Stability

open access: yesFrontiers in Earth Science, 2022
Rainfall is the main factor leading to the landslide of expansive soil slope. To deeply understand the instability mechanism of expansive soil slope under rainfall conditions, it is necessary to clarify the strength attenuation mechanism of expansive ...

An elasto-plastic model for unsaturated soil incorporating the effects of suction and degree of saturation on mechanical behaviour [PDF]

open access: yes, 2003
The paper presents an elasto-plastic model for unsaturated soils that takes explicitly into account the mechanisms with which suction affects mechanical behaviour as well as their dependence on degree of saturation.

Spectroscopy to characterize expansive soils

open access: yes2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
Expansive soils are major geotechnical hazards that pose several problems on engineering structures causing billions of dollars of damage in many parts of the world especially at places where there are significant climatic differences between dry and wet periods (Gourley et al., 1993; Nelson and Miller, 1992).

Effect of compaction pressure on consolidation behaviour of unsaturated silty soil [PDF]

open access: yes, 2004
YesThe effect of compaction pressure on subsequent soil behaviour during isotropic consolidation has been investigated by conducting controlled-suction triaxial tests on samples of an unsaturated compacted silty soil.

Modelling and calculating lateral pressure of expansive soil-EPS inclusion-retaining wall system

open access: yesYantu gongcheng xuebao, 2021
The thermal fields and thermal expansion are used to simulate the moisture fields and swelling of expansive soils upon wetting in this study. The thermal-mechanical coupled finite element analysis is employed to simulate the "expansive soil-EPS inclusion-

Sand shape effect on the hydraulic conductivity and compressibility of clay sand liners

open access: yesFrontiers in Materials
Designing environmental protection barriers requires careful consideration in the choice of coastal sand material used in clay-sand mixtures. The purpose of this study is to present a comparison and guide between two methodologies to investigate sands of
