Characteristics of deformation and defect of shield tunnel in coastal structured soil in China Open
Shield tunnel is a type of linear underground structure assembled by lining segments, characterized with long joint, weak stiffness, and strict deformation control requirement. The situation of the long-term deformation and defect of the s…
Unraveling the Stray Current-Induced Interfacial Transition Zone (ITZ) Effect on Sulfate Corrosion in Concrete Open
The rail transit in sulfate-rich areas faces the combined effects of stray current and salt corrosion; however, the sulfate ion transport and concrete degradation mechanisms under such conditions are still unclear. To address this issue, n…
Real-Time Prediction of Strata Conditions in Front of EPB Shield based on Bayesian Algorithms Open
Prediction of strata conditions is one of the essential tasks in shield tunneling. the variability of strata and the uncertainty of construction bring greater challenges to prediction. The uncertainty was introduced to improve the accuracy…
Dual heterogeneous Cu–Al2O3/Cu laminated composite with high strength and ductility prepared by accumulative roll bonding Open
Cu–Al2O3/Cu laminated dual heterogeneous microstructure composites with alternating coarse/fine grain distributions were prepared using a combination of accumulative roll bonding and annealing processes. The average layer thickness of the …
Effect of seepage on soil arching effect in deep shield tunnel Open
Shield tunneling and post-tunneling steady seepage are accompanied by stress and displacement variations, which could induce and influence the soil arching effect. Although there are many studies on the tunneling-induced soil arching effec…
Undrained cylindrical cavity expansion/contraction in stiff clays using a two‐surface plasticity model Open
This paper presents a semi‐analytical solution of undrained cylindrical cavity expansion/contraction problem using a two‐surface plasticity model for natural stiff clays from the view point of poromechanics. The present solution reduces th…
Analytical and Semi-Analytical Solutions for Describing Tunneling-Induced Transverse and Longitudinal Settlement Troughs Open
It is an ongoing problem to develop a solution to predict ground deformation induced by shallow tunnels construction in dry soils. This study proposes a closed-form elastic analytical solution and a plastic analytical solution for calculat…
Laboratory characterization and modelling of the thermal-mechanical properties of binary soil mixtures Open
Binary soil mixtures are extensively used in the construction of geothermal-related earth structures such as geothermal energy piles (GEP), ground source heat pumps (GSHP) and earth air tunnel heat exchangers (EATHE). An evaluation of the …
EP10.14: Value of fetal intelligent navigation echocardiography (5D heart) and virtual intelligent sonographer assistance (VIS‐assistance) in the display of key diagnostic elements in basic fetal echocardiographic views Open
To evaluate the value of 5D heart and virtual intelligent sonographer assistance (VIS-assistance) in the display of key diagnostic elements in basic fetal echocardiographic views. The heart volume data of 209 normal fetuses were collected …
OP11.02: Smart‐planes fetal heart automatically generate fetal ventricular outflow tract views and to quantitate fetal aortic and pulmonary artery dimensions Open
To explore the feasibility of smart-planes fetal heart (S-Planes FH) software in visualisation of the fetal ventricular outflow tract views, and to evaluate the agreement and reliability of S-Planes FH software in determining fetal aortic …
