Analysis of Nonlinear Consolidation Characteristics of Soil Around Tunnels Considering Self-Gravity Stress

open access: yesShanghai Jiaotong Daxue xuebao
Considering the self-gravity stress of the soil around the tunnel, a two-dimensional nonlinear consolidation control equation for saturated soil was established, and solved using the alternating implicit difference method. The correctness of the solution

Finite Analytic Method for One-Dimensional Nonlinear Consolidation under Time-Dependent Loading

open access: yesShock and Vibration, 2017
For one-dimensional (1D) nonlinear consolidation, the governing partial differential equation is nonlinear. This paper develops the finite analytic method (FAM) to simulate 1D nonlinear consolidation under different time-dependent loading and initial ...

Two-Dimensional Electroosmotic Consolidation Theory of Nonlinear Soil Voltage Distribution Characteristics

open access: yesAdvances in Civil Engineering, 2019
Soil voltage is generally assumed to show a linear relationship with distance from the cathode according to the established electroosmotic consolidation equation. However, this assumption is inconsistent with experimental results.

Experimental study on consolidation characteristics of deep clayey soil in a typical subsidence area of the North China Plain

open access: yesFrontiers in Environmental Science, 2022
Land subsidence is an important environmental problem in the North China Plain (NCP). A typical subsidence area mainly located on adjoining areas of Beijing and Hebei provinces was selected to study the consolidation characteristics of deep clayey soil ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

One-dimensional coupled model for large-deformation electroosmotic consolidation and heavy metal ion migration of silt

open access: yesYantu gongcheng xuebao, 2022
Dewatering and metal removal of silt can be obtained by applying electrokinetics. A coupled model for one-dimensional electroosmosis consolidation and ion migration, called ECT1, is proposed.
