Stress–strain Behaviour of Bio-desaturated Sand Under Undrained Monotonic and Cyclic Loading
Author(s) Kangda Wang, Jian Chu† Shifan Wu‡ Jia He§ Abstract Microbial (or bio-) desaturation is a new method for mitigation of the liquefaction hazard of sand. In this paper, a series of monotonic and cyclic triaxial tests was performed on bio-desaturated...
Ground Waste Glass–carbide Lime as a Sustainable Binder Stabilising Three Different Silica Sands
Author(s) Nilo Cesar Consoli, Mariana da Silva Carretta, Lucas Festugato, Helena Batista Leon, Lennon Ferreira Tomasi Abstract Waste glass is a solid residue usually available near urban centres, where it is discarded after being used as a container for one of...

Application of Discrete-Element Numerical Simulation for Calculating the Stability of Dangerous Rock Mass: A Case Study
Author(s) Chong Shi ; Bo Yang ; Yiping Zhang ; and Junxiong Yang FULL TEXT Abstract An unstable rock mass is a common geological hazard in water conservancy and hydropower engineering in southwest China. The mechanical properties of a rock mass joint and the...
Interface Shear Behavior of Cementing Underground Mine Backfill
Author(s) Shuai Guo ; Mamadou Fall ; and Sada Haruna Abstract This paper presents the findings from an experimental investigation that was conducted to assess the shear behavior and the changes in the shear behavior and strength parameters for cemented paste...
Liquefied Strength and Its Relationship to Effective Stress
Authour(s) Robb Eric S. Moss, Ph.D., P.E., F.ASCE Abstract The residual strength of liquefied soil (su,r) is a large-strain strength variable often used for forecasting the seismic stability of dams, embankments, and mine tailings. This variable is usually...
