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 ConferencesThe 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

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 ...

Buildings, 2023 Soft soil has the characteristics of high compressibility, large void ratio, and strong structure. Therefore, it is more likely to cause surface subsidence or even surface cracking and collapse when laying oil and gas pipelines in soft soil areas through

Persistent scatterer interferometry to monitor mining related ground surface deformation for data-driven modelling [PDF]
, 2006 The monitoring, interpretation and prediction of gradual ground surface deformation are critical factors in the understanding of earth systems. In many parts of the world, particularly in coastal areas where resources are often easily transportable and ...
