Criteria for rapid sliding II.: thermo-hydro-mechanical and scale effects in Vaiont case [PDF]

open access: yes, 2010
Thermally induced excess pore pressures have been included into a two-wedge evolutive model of Vaiont landslide. The problem requires the solution of a system of four coupled balance equations for the shear bands and the surrounding rock as well as the ...

Influence of effective stress on swelling pressure of expansive soils

open access: yesE3S Web of Conferences, 2016
The volume change and shear strength behaviour of soils are controlled by the effective stress. Recent advances in unsaturated soil mechanics have shown that the effective stress as applicable to unsaturated soils is equal to the difference between the ...

Fine Characterization Method of Concrete Internal Cracks Based on Borehole Optical Imaging

open access: yesApplied Sciences, 2022
The internal cracks of concrete are very important in the safety evaluation of structures, but there is a lack of fine characterization methods at present.

Criteria for rapid sliding I.: a review of Vaiont case [PDF]

open access: yes, 2010
Vaiont slide has been represented by a model of two interacting evolutive wedges. Mass conservation during the motion implies that the upper wedge transfers mass to the lower one through an internal shearing plane.

A Simulation Study on the Swelling and Shrinking Behaviors of Nanosized Montmorillonite Based on Monte Carlo and Molecular Dynamics

open access: yesGeofluids, 2021
Montmorillonite is the main mineral source for the swelling and shrinking of expansive soils. The macroscopic phenomena of soil are affected by the action of deep-level nanosized minerals. In order to illustrate the nanoscale mechanism from the molecular

Integrity Analysis of the Sheath Considering Temperature Effect under Deep and Large-Scale Multi-Section Hydraulic Fracturing

open access: yesEnergies, 2021
Different operations make the borehole temperature change and cause periodic stresses, which often cause variations in the stress state of the sheath or damage. In this paper, the effect of temperature on sheath integrity is investigated.

Study on Failure Mechanism of Soil–Rock Slope with FDM-DEM Method

open access: yesSustainability, 2022
A discrete-continuous coupling analysis method based on FLAC2D/PFC2D is established with the help of the program’s own FISH language and Socket O/I data transfer interface. According to the statistical characteristics of the mesostructure of the slope site, the computer stochastic simulation method is used to construct the mesostructure model of the ...

Nonlinear Viscoelastic Compaction in Sedimentary Basins [PDF]

open access: yes, 2010
In the mathematical modelling of sediment compaction and porous media flow, the rheological behaviour of sediments is typically modelled in terms of a nonlinear relationship between effective pressure $p_e$ and porosity $\phi$, that is $p_e=p_e(\phi ...

Study of Impact of Sediment on the Stability of Salt Cavern Underground Gas Storage

open access: yesEnergies, 2023
The utilization of sediment voids for natural gas storage represents the future direction of salt cavern underground gas storage (UGS) in China. In this study, we first analyzed the way in which the sediment interacts with the salt caverns and the ...

Study of Material Composition Effects on the Mechanical Properties of Soil‐Rock Mixtures [PDF]

open access: yesAdvances in Civil Engineering, 2018
Soil‐rock mixtures are often seen in geological deposits. Mechanical properties of these mixtures are controlled by microstructural characteristics such as rock size distribution, rock shape, locations, and content. The effects of material composition on soil‐rock mechanical properties were studied in the laboratory. The soil‐rock material was screened
