Study of in situ stress inversion of deeply incised valleys considering the river evolution process [PDF]

Scientific Reports
The study of the in situ stress field is significant for the stability of large underground caverns near deep V-shaped valleys. Tectonic movements, gravity and river erosion have a great influence on the formation of the modern stress field.

In situ stress inversion using nonlinear stress boundaries achieved by the bubbling method

Journal of Rock Mechanics and Geotechnical Engineering
Due to the heterogeneity of rock masses and the variability of in situ stress, the traditional linear inversion method is insufficiently accurate to achieve high accuracy of the in situ stress field. To address this challenge, nonlinear stress boundaries

A modified initial in-situ Stress Inversion Method based onFLAC3D with an engineering application

Open Geosciences, 2015
To improve the accuracy of an initial in-situstress field determined by inversion, we describe a modified initial in-situ stress inversion method that uses partialleast-squares regression based on FLAC3D.
