Numerical study on the deformation of soil stratum and vertical wells with gas hydrate dissociation [PDF]
Acta Mechanica Sinica/Lixue Xuebao, 2016 Gas hydrate (GH) dissociates owing to thermal injection or pressure reduction from the well in gas/oil or GH exploitation. GH dissociation leads to, for example, decreases in soil strength, engineering failures such as wellbore instabilities, and marine landslides. The FLAC3D software was used to analyze the deformation of the soil stratum and vertical

A Method for Calculating Soil Deformation Induced by Shielded Tunneling in Ground Stratum with Cavities [PDF]
Symmetry, 2021 The existence of cavities in shallow ground strata is one of the important causes of urban road collapse under the disturbance of tunnel excavation. Thus, this paper discusses the convergent deformation mode of ellipsoidal cavities. To this end, the convergent deformation of a cavity and the overall displacement of a tunnel were comprehensively ...

Sensitivity analysis of counterweight double-row pile deformation to weak stratum parameters
Scientific Reports, 2023 Abstract In order to investigate the sensitivity of weak soil parameters on the deformation of balanced double-row piles, a case study was conducted in a deep foundation pit project in Shenzhen City. A variety of analysis methods, including numerical simulation, field measurements, orthogonal experiments, and ...
