Shanghai center project excavation induced ground surface movements and deformations
Frontiers of Structural and Civil Engineering, 2017Empirical data on deep urban excavations can provide designers a significant reference basis for assessing potential deformations of the deep excavations and their impact on adjacent structures. The construction of the Shanghai Center involved excavations in excess of 33-m-deep using the top-down method at a site underlain by thick deposits of marine ...

Modelling of surface ground deformations in the Phlegraean Fields volcanic area, Italy
Bulletin Volcanologique, 1984A preliminary finite elements model of the ground deformations observed at Phlegraean Fields is proposed. The model assumes an oblate-spheroid magma chamber at the depth of 5.4 km with major semiaxis of 1.5 km and minor semiaxis of 0.75 km. The dimensions of the magma chamber have been evaluated by using a thermal model based on the assumptions that a ...

Analysis on ground surface deformation induced by the subway double tunnels construction
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011The relative position change of metro double tunnels and construction of the sequence will induce the surface deformation and the interaction of the tunnel lining. It is more concerned about these issues in tunnel design. In this paper, It is the main purposes to analyze the metro double tunnels surface deformation which induced by the position changes

Numerical Simulation and Numerical Differential Computation of Bending Deformation of Ground Surface
Applied Mechanics and Materials, 2012The ground subsidence due to backfill mining is different from those caused by other mining methods. It’s practically important to analyze the influence of ground deformation due to backfill mining on the buildings above the ground accurately. An example of analysis of ground deformation on an iron mine in the east of Hebei was given in this paper ...

Residual Stress and Deformation Energy Under Ground Surfaces of Brittle Solids
CIRP Annals, 1986This work deals with the determination and description of the deformation energy, which is accumulated under the surface of brittle solids, especially those of optical glass, during the free abrasive grinding process. The distribution of deformation energy density in depth under the ground surface was investigated in this work.

Abstract Objective—To determine whether solar load distribution pattern on a solid nondeformable ground surface is the product of contact erosion and is the mirror image of load distribution on a deformable surface in horses. Animals—30 clinically normal horses.

Observation of ground surface deformation in coastal areas by SAR Interferometry
2017Sea-level rise is one of the most unavoidable consequences of anthropogenic climate change. Coastal managers need to anticipate impacts and adaptation needs at local scale, which implies considering all components of sea-level changes, including vertical ground motions.

Ground Surface Deformation Analysis of Quasi Rectangular EPB Shield Tunneling
2018The first quasi rectangular shield tunnel in China was developed during the construction of Ningbo Metro Line 3. Based on the Mindlin solution, this paper presents the computerized outcome of the ground surface deformation caused by the following three factors: the horizontal excess pressure at the excavation face, the friction between the shield skin ...
