Ground Surface Deformation Sensor Based on Cable Impedance

Applied Mechanics and Materials, 2012
In order to measure ground surface deformation, a sensor based on cable impedance change is studied in this paper. This sensing cable has elastic double helical structure with much larger measurement range than optical fiber distributed deformation technology.

A Technique for Surveying of Ground Surface Deformations in Mine Field

Journal of Mining Science, 2018
The 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.

Effect of Wall Deformation on Dewatering-Induced Ground Surface Settlement

Journal of Shanghai Jiaotong University (Science), 2020
In practice, dewatering for pressure relief is commonly undertaken during ongoing excavation to secure bottom stability against basal upheaval. Simultaneously, through unloading, wall deflection is obviously observed. Noticing that both cause soil deformations, this research is to study the effect of wall deformation on dewatering-induced settlement. A

Ground surface displacements and tilt monitoring for reconstruction of reservoir deformations

International Journal of Rock Mechanics and Mining Sciences, 2011
Abstract Surface deformation generated during hydrocarbon production, and waste or water reinjection, can be used to indirectly monitor subsurface deformation sources. Forward and inverse models previously studied are mostly based on the nucleus of strain approach and are focused on measurements of vertical or horizontal deformations.

SPH Simulation for Large Deformation of Ground Surface Caused by Faulting

Journal of Earthquake and Tsunami, 2018
Once 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 ...

Role of Ground Surface Deformation in Volcano Monitoring

2014
What can be learned about the inner working of volcanoes by studying how they change shape or deform? What role does InSAR play in volcano deformation studies, and what other techniques are useful for studying deforming volcanoes? By what means and to what extent can volcanic eruptions and their impacts be forecast using deformation and other types of ...

The deformation of the ground around surface faults

Bulletin of the Seismological Society of America, 1961
Abstract 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 ...

Ku-band ground-based SAR experiments for surface deformation monitoring

2015 IEEE 5th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2015
Continuous 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.
