Excavations near an existing tunnel are frequently encountered in underground construction. The excavation–soil–tunnel interaction mechanism is not yet fully understood, notably the long-term behavior. This study carried out three-dimensional centrifuge test of subjected to a nearby excavation saturated kaolin clay. Emphasis put on behaviors ground and regarding undrained shear strength, excess pore-water pressure, horizontal earth compression behavior, settlement, bending moment. T-bar...
Shield tunneling and post-tunneling steady seepage are accompanied by stress displacement variations, which could induce influence the soil arching effect. Although there many studies on tunneling-induced effect, research about effect of is extremely lacking. In this study, a numerical model firstly established verified field data. Then, series models, whose simulation method adopting conformal mapping technique, to study evolution deep-buried post-construction seepage. The results indicate...
This paper presents observed arching-induced ground deformation and stress redistribution behind braced excavation using the top-down construction method. The soil properties around were determined by laboratory field tests. deformation, displacement vector, strain path, principal strain, maximum shear lateral earth pressure, pore water effective path are presented based on measured data. majority of wall is under volumetric expansion, indicating consolidation, creep behavior, or a...
In this study, a new 3D numerical model that considers the circumferential joint, longitudinal bolt, grout pressure, jacking force and constraint of shield on linings is developed to derive deeper insights into lining uplift behavior during tunneling. The analysis conducted using ANSYS, which verified by case history in soft soils. Revealed both measurements calculation results, it found due tunneling soils can be divided three stages: dislocation, stretch steady deformation stages,...
