The deformation of the ground around surface faults
Bulletin of the Seismological Society of America, 1961Abstract A rectangular dislocation surface (i.e., a surface across which there is a discontinuity in the displacement vector) is used as a model of a vertical transcurrent fault. The results of Steketee (1958a) are employed to derive, in analytical form, the displacement field throughout a semi-infinite elastic medium due to such a ...

A Technique for Surveying of Ground Surface Deformations in Mine Field
Journal of Mining Science, 2018The application variants of remote metering technologies, such as laser scanning and airborne imaging, are discussed. Based on the international experience gained in photogrammetry, a technique is proposed for surveying using a camera, quadcopter, electronic tacheometer and an appropriate software support.

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.

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 ...

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 ...

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 ...

Time Series Forecasting Model of Ground Surface Deformation for Coal Mine Shaft
Advanced Materials Research, 2012Some displacement and deformation for the mine shaft over past many years’ working may occur, which will cause heavy harm to both shaft itself and workers in well. Curtain grouting is one of efficient methods to protect the shaft and the earth’s surface around the shaft from the harm.

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

Predicting ground surface deformation induced from CO2 plume movement using machine learning
Australian Energy Producers JournalCarbon capture and storage (CCS), which involves injecting carbon dioxide (CO2) into subsurface, is an increasingly popular process for mitigating human caused greenhouse gas emissions. In order to ensure the safety and efficacy of CCS implementation, it is necessary to possess a comprehensive understanding of the complex behaviour of CO2 plumes within
