Deformation of transfersomes dispersed in hydrated deep eutectic solvent in stratum corneum
Chemistry LettersAbstract The deformation of transfersomes (TFs) dispersed in deep eutectic solvents and applied to the stratum corneum (SC) was evaluated by small-angle X-ray scattering. We found that TFs permeated the SC, while the regularity and period of the multilayer structure of TFs deformed significantly, depending on the SC location and the time

Characteristics and mechanism of large deformation of squeezing tunnel in phyllite stratum
Canadian Geotechnical JournalThe Maoxian Tunnel in Sichuan, China has experienced significant deformation and supporting failure in the surrounding phyllite rock. To address this problem, on-site engineering geological investigation and testing methods were deployed in the present study to examine the characteristics and mechanism of deformation in the tunnel.

Influence of Cavity above Tunnel on Stratum Deformation and Failure in Urban Tunnelling
Applied Mechanics and Materials, 2012In order to study the influence of cavity above the tunnel on stratum deformation and failure in urban tunnelling, the model test method was adopted based on the parameters of the stratum and tunnel section size in Beijing subway. The stratum responses were obtained under the conditions without ground cavity and with ground cavity above the tunnel. The

Numerical Analysis of Metro Tunneling-Induced Stratum Deformation and Settlement by Using FLAC3D
2010 International Conference on Intelligent Computation Technology and Automation, 2010Constructing metro tunnel in shallow stratum destroys surrounding stratum structure, causing corresponding deformation and settlement of stratum. So it’s very important to accurately predict stratum deformation and settlement for metro tunneling. In this paper, the features of FLAC3D and built-in material constitutive model are firstly analyzed, then ...

Deformation and Filtration Near a Well in a Porous Stratum with Linear Memory
International Applied Mechanics, 2003The linearized equations for saturated elastic porous media and for surrounding elastic rock are solved simultaneously; and the Volterra principle is used to derive an integro-differential filtration equation for a homogeneous weakly compressible fluid in an axisymmetric stratum with linear memory and central well. An analytical expression for porosity

Finite-element (FE) simulations are increasingly providing a versatile environment for conducting lateral ground deformation studies. In this environment, mitigation strategies may be assessed in order to achieve economical and effective solutions. On the basis of a systematic parametric study, three-dimensional FE simulations are conducted to evaluate

Observation and evaluation of soil stratum deformation in reclamation area under ocean tides
Canadian Geotechnical JournalReclamation areas in coastal regions serve as primary human settlements, where groundwater undergoes fluctuations due to changes in ocean tides, resulting in deformation variations within the soil stratum. In this paper, the UWFBGs (ultra-weak fiber Bragg grating arrays) technique with micro strain accuracy and meter-scale resolution was used to ...
