Analysis of deformation mechanism of soft soil reinforcement by vacuum preloading
Rock and Soil Mechanics, 2021 Based on the changes of total stress and pore water pressure in the spring model, the mechanism of vacuum preloading consolidation is studied by theoretically discussing the consolidation behavior of soil in vertical and horizontal directions with ...

Mechanical response of red clay under different stress paths and loading and unloading rates
Shuiwen dizhi gongcheng dizhiDuring foundation pit excavation, soils are subjected to multiple coupled factors and present complex failure characteristics, making it difficult to capture their mechanical behavior through single-factor analysis. In this study, the natural red clay in

Mechanical response of grading loading and unloading of backfill sand under confinement constraint
Shenzhen Daxue xuebao. Ligong ban, 2023 In subgrade and levee projects, local subsidence problems often occur due to insufficient compaction of backfill sand. In order to reduce the possibility of such damage, the three-dimensional stress-strain testing technology is used to study the ...

Stress-strain responses for continuous orthogonal strain path changes with increasing sharpness [PDF]
, 2007 In this article a series of non-proportional orthogonal tests with continuous strain paths are presented. Mild steel was investigated on a biaxial test device that was specifically developed to examine strain path sensitivity.

Non-convexity and stress-path dependency of unsaturated soil models
, 2008 Yield surfaces for unsaturated soils are usually non-convex if the size of the yield surface has to increase with increasing suction. An expanding yield surface with increasing suction is crucial for modelling the volume collapse due to wetting.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
