RISHydromechanical Behaviors of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: In this paper, the hydromechanical behavior of unsaturated soils is explored. A constitutive model is proposed to describe the coupled hydraulic and mechanical behavior of unsaturated soils. The compression stiffness ...
Experimental Investigation and Modeling of the Hydraulic Conductivity of Saturated Bentonite–Claystone Mixture
Publisher: ASCE
Abstract: Mixtures composed of MX80 bentonite and crushed Callovo-Oxfordian (COx) claystone have been considered as one of the promising sealing/backfilling materials in French deep geological disposal for radioactive waste. One of ...
Investigation of Suction Effects Due to Stress Release with Compacted MX80 Bentonite
Publisher: ASCE
Abstract: In this study, the suction induced by stress release was investigated by measuring the suction of instantaneously unloaded MX80 bentonite specimens after wetting in an oedometer either under different vertical stresses or ...
Stress Release–Induced Suction in Unsaturated MX80 Bentonite Pellet and Powder Mixtures
Publisher: American Society of Civil Engineers
Abstract: In this study, a series of suction-control oedometer tests were conducted on unsaturated and saturated MX80 bentonite pellet/powder mixtures. The mixture samples were imposed with various suctions from 0 to 113 MPa ...
Large-Strain Consolidation Analysis for Clayey Sludge Improved by Horizontal Drains
Publisher: ASCE
Abstract: The use of prefabricated horizontal drains (PHDs) with combined surcharge and vacuum preloading is an effective improvement approach for dredged clayey slurries. However, there is no large-strain analysis method for ...
Large-Strain Consolidation of Sludge in Geotextile Tubes Considering Vacuum-Induced Rapid Consolidation and Soil Reconstitution
Publisher: American Society of Civil Engineers
Abstract: Clogging represents a crucial factor severely hindering the vacuum preloading treatment for clayey sludge. However, the underlying mechanism of this occurrence remains insufficiently investigated, limiting the application ...
Tensile Strength of Fiber-Reinforced Soil
Publisher: American Society of Civil Engineers
Abstract: The tensile strength of soil is an important mechanical parameter that controls the development of tension cracks. In this study, randomly distributed polypropylene fibers were employed to improve soil tensile behavior. ...
Insights into Determination of Gas Breakthrough in Saturated Compacted Gaomiaozi Bentonite
Publisher: ASCE
Abstract: Gas breakthrough pressure is of great importance for evaluating the sealing efficiency and assessing the long-term performance of saturated buffering materials with low permeability in the deep geological disposal of ...
One-Way Cyclic Behavior of Saturated Clay in 3D Stress State
Publisher: American Society of Civil Engineers
Abstract: The soil stress state is three-dimensional (3D) in many applications, including the case of traffic loading. This aspect has been rarely undertaken in the laboratory. This paper investigates the one-way cyclic behavior of ...
