Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

open access: yesDeep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Silo centrifuge modeling - Influence of gravity on granular flow

open access: yes, 2016
The flow of granular material through an orifice has been a subject of numerous studies for decades due to its importance for proper industrial silo design. The most widely accepted law that predicts the flow rate of grains trough an orifice was proposed

Geotechnical centrifuge under construction

open access: yesEos, Transactions American Geophysical Union, 1982
Modifications are underway at the National Aeronautics and Space Administration (NASA) Ames Research Center in California to transform a centrifuge used in the Apollo space program to the largest geotechnical centrifuge in the free world. The centrifuge, to be finished in August and opened next January, following check out and tuning, will enable ...

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Difference characteristics of stress similitude for geotechnical centrifuge modelling and design criteria

open access: yesYantu gongcheng xuebao, 2018
The advantage of geotechnical centrifuge modelling is founded on the exactly similar stress levels and distribution between models and prototypes. To recognize the differences and characterization parameters of stress similitude of model and prototype is
