A practical method for predicting ground surface deformation induced by the artificial ground freezing method

Computers and Geotechnics, 2021
Abstract The Artificial ground freezing (AGF) method is a reliable and environmentally friendly technique used for ground improvement to address adverse geotechnical conditions, and it has been widely used in the civil engineering field. However, frost heave and thaw settlement during the freeze–thaw process is inevitable, and excessive deformation ...

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.

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.

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 ...

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.

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
