A simplified approach of numerical seismic model updating for deep braced excavation using centrifuge test

open access: yesResults in Engineering
The numerical modeling and centrifuge test are very effective tools in demonstrating the actual behavior of deep excavation, but the preciseness in verification is crucial.

Effect of Duxseal on Horizontal Stress and Soil Stiffness in Small-Amplitude Dynamic Centrifuge Models [PDF]

open access: yes, 2022
The constitutive behavior of soil is stress dependent. Therefore, geotechnical centrifuges are widely used to replicate full-scale stress fields, thereby ensuring the correct soil response within reduced-scale centrifuge models.

Analysis of Vertical Earth Pressure Acting on Box Culverts through Centrifuge Model Test

open access: yesApplied Sciences, 2021
Due to the lack of surface space, most structures are heading underground. The box culvert is underground infrastructure and serves to protect the buried structure from the underground environments, but it has a different characteristic from other ...

Prefailure Deformation of Nailed Deep Excavations under Surcharge by Centrifuge Model Test

open access: yesAdvances in Civil Engineering, 2021
To study prefailure deformations in nailed deep vertical excavations under various surcharges, four centrifuge tests were used to explain the lateral deformation of facing, the fracture mechanism of cement facing, and the settlement profile of the ground

Gas production behaviour of gas hydrate–bearing clayey-sand during depressurization: novel in-flight centrifuge modelling [PDF]

open access: yesE3S Web of Conferences, 2023
Gas hydrate-bearing sediments (GHBS) are vastly distributed around the globe. While gas production attempts are made through GHBS, long-term production remains a challenge due to complex inter-related mechanisms involved. Better understating of long-term

Centrifuge Model Tests of Nailed Soil Slopes

open access: yesSoils and Foundations, 1998
This paper presents the results of 24 centrifuge model tests of nailed soil slopes and vertical walls, constructed out of dry Leighton buzzard sand. The walls were initially supported by fluid pressure from flexible rubber bags against the face, and excavation was modelled by gradually draining the fluid from the bags. The finished model walls were 200

Analysis of Horizontal Earth Pressure Acting on Box Culverts through Centrifuge Model Test

open access: yesApplied Sciences, 2022
Underground space is being utilized due to the saturation of surface ground. The box culvert, as a representative infrastructure that has moved underground, is installed to protect such fixtures as electricity and gas.
