The process of supergene deformation is also the process of ground deformation and destruction. Many geohazards occurred frequently in the Three-Gorges region are related to the development of supergene deformation structure.
Based on the design of the mat foundation of a tall building,some major problems are analyzed and discussed in this article,such as mat foundation styles,determination of subgrade bearing capacity and calculation method of subsoil deformation control.
The principal causes of a fairly small value n include: a fairly great deformation of foundation; the interpile soil on the upper part are sand filling with fairly great modulus; pile and sand have approximate modulus of deformation.
Composite foundation can reduce deformation of foundation. Additional stress and compression modulus are the two important parameters of deformation calculation on composite foundation. And the value of additional stress and deformation modulus are discussed.
It has been shown that the stresses and deformations in the tank under differential settlements are dependent on its geometric parameters. Thus current empirical criteria for allowable deformation of foundation that is independent of geometric parameters seems unreasonable viewed from the structural perspective.
Currently InSAR provides the ability to map accurate DEM and measure ground deformation to sub-centimeter accuracy.
Co-seismic ground deformation and source parameters of Mani M7.9 earthquake inferred from spaceborne D-InSAR observation data
We obtain the co-seismic ground deformation field of the Mani M7.9 earthquake on November 8, 1997 through three-pass differential interferometric processing.
In this way it is possible to increase the spatial resolution of the measured ground deformation, while still maintaining the same level of precision as a CGPS network comprised entirely of dual-frequency GPS receivers.
Earthquakes, ground deformation, and increased geothermal activity at Long Valley caldera after mid-1980 suggest the possibility of a volcanic eruption in the near future.
