Undrained creep behavior of CO2 hydrate-bearing sand and its constitutive modeling considering the cementing effect of hydrates

Autor: Masaki Yoshimoto, Sayuri Kimoto

Publikováno v: Soils and Foundations, Vol 62, Iss 1, Pp 101095- (2022)

A technique for carbon dioxide (CO2) capture and storage using CO2 hydrates where CO2 is stored as solid hydrates in the seabed ground, is attracting attention. Shallow sediments may be the most suitable seabed ground for CO2 hydrate storage because

Numerical Analysis of Damaged River Embankment during the 2011 Tohoku Earthquake Using a Multiphase-Coupled FEM Analysis Method

Autor: Li Chen, Sayuri Kimoto

Publikováno v: Geofluids, Vol 2018 (2018)

According to the investigation and restoration report by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT, 2011), 1195 river embankments were damaged in Tohoku region during the 2011 Tohoku earthquake. The failures of the river emban

Stability Analysis of Methane Hydrate-Bearing Soils Considering Dissociation

Autor: Hiromasa Iwai, Sayuri Kimoto, Toshifumi Akaki, Fusao Oka

Publikováno v: Energies, Vol 8, Iss 6, Pp 5381-5412 (2015)

It is well known that the methane hydrate dissociation process may lead to unstable behavior such as large ground deformations, uncontrollable gas production, etc. A linear instability analysis was performed in order to investigate which variables ha

Formulation of a constitutive model for three-phase porous materials and the skeleton stress

Autor: Sayuri Kimoto, Fusao Oka

Publikováno v: Soils and Foundations. 60:1001-1010

In the present note, constitutive equations for air-water-solid three-phase porous materials were formulated considering thermodynamics in the context of continuum mechanics. In the formulation, the complementary energy function was used and the inte
