GNSS Ground deformation observation network optimization assisted using prior InSAR-derived ground surface deformation and multiscale iteration estimation

International Journal of Digital Earth
Ground surface deformation must be monitored to understand and prevent geological hazards. Global navigation satellite system (GNSS) technology has been widely used in deformation monitoring; however, current GNSS station layout strategies are often ...

Distributed Fiber Optic Strain Sensing for Geomechanical Monitoring: Insights from Field Measurements of Ground Surface Deformation

Geosciences, 2021
In recent years, distributed fiber optic strain sensing (DFOSS) technology has demonstrated a solution for continuous deformation monitoring from subsurface to surface along the wellbore. In this study, we installed a single-mode optical fiber cable in a

Extrusion deformation process of ground surface during the Lushan earthquake in China

Geodesy and Geodynamics, 2017
Based on finite element method, the extrusion deformation process of ground surface during the Lushan earthquake (April 20, 2013) is investigated in this work. In order to construct the finite element model of Lushan earthquake structure, the geophysical

Prognosis of Ground Surface Deformation of the Victoria Mine –Slănic Prahova Saline [PDF]

MATEC Web of Conferences
The Victoria mine, from Slănic Prahova Saline operated in the period 1970-1992 and was mined with small rooms and square pillars, on 11 overstory levels, of 16 m high. It resulted in a volume of mining voids of 7.4 million m3, which led to the pronounced

Building Deformation Prediction Based on Ground Surface Settlements of Metro-Station Deep Excavation

Advances in Civil Engineering, 2018
Building deformations are not only closely related to the distance from the building to metro-station excavation but also related to the relative positions of the building and metro-station excavation.

Ground Surface Deformation in the Hanging Wall of the Jinshandian Underground Iron Mine in China

Frontiers in Earth Science, 2022
When sublevel caving is used in metal mines, the stress state in the rock mass that initially existed around the mined-out area will be destroyed. This will lead to the rock strata deforming and moving and also, potentially, to large-scale collapse and ...

Experimental Research on the Settlement Feature of Two Ground Deformation Modes Induced by Tunnelling

Mathematics, 2023
Two ground deformation modes, i.e., the arching mode and collapsing mode, may be caused by tunnel excavation. However, the development of the ground deformation corresponding to the two modes is unclear.

Study on the law of residual deformation in mining subsidence area and its influence on the safety of ground buildings

Frontiers in Earth Science, 2023
After the mining subsidence area reaches the stable state of surface movement, due to the continuous existence of the mutual extrusion and activation state between rock strata, the movement of particles, rock creep, and soil compression will affect the ...

Ground Deformation and Permafrost Degradation in the Source Region of the Yellow River, in the Northeast of the Qinghai-Tibet Plateau

Remote Sensing, 2023
The source region of the Yellow River (SRYR) is situated on the permafrost boundary in the northeast of the Qinghai-Tibet Plateau (QTP), which is an area highly sensitive to climate change. As a result of increasing global temperatures, the permafrost in
