Gas production behaviour of gas hydrate–bearing clayey-sand during depressurization: novel in-flight centrifuge modelling [PDF]
E3S 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

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

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

Centrifuge Model Tests of Nailed Soil Slopes
Soils 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

The Deformation Characteristics of Weak Foundation with High Back Siltation in the Immersed Tunnel
Advances in Materials Science and Engineering, 2018 The deformation characteristics of a weak foundation with high back siltation in an immersed tunnel lack empirical data; however, the calculation method and control of foundation settlements are highly important to tunnel design and construction.
