SPH Simulation for Large Deformation of Ground Surface Caused by Faulting
Journal of Earthquake and Tsunami, 2018Once a large deformation appears on the ground surface due to faulting during an earthquake, it may cause severe damage to infrastructure systems. A numerical simulation method that provides accurate prediction on the deformation of the ground surface is very useful for examining the performance of infrastructure systems subjected to a deformation of ...

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 ...

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.

Ku-band ground-based SAR experiments for surface deformation monitoring
2015 IEEE 5th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2015Continuous monitoring of ground deformation on high-risk areas is of great importance for the study of landslide mechanisms as well as to serve as an early warning system before the triggers of hazardous events. A new ground-based synthetic aperture radar (GBSAR) has been developed and installed at selected landslide-prone areas in Malaysia.

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
