... ABSTRACT: Stability and potential failure mode of tunnels and underground rock caverns is directly related to the magnitude and orientation of the in-situ rock stress. In some cases, the high horizontal in-situ stress is essential in maintaining cavern stability, whilst in other cases the high...

... ABSTRACT: For large underground cavern established in bank slope with ‘V’ shape valley, estimation of in-situ rock stress and failure of wall rock is very signification, not only for prevention from potential failure, large deformation, and instability of caverns, but also for the optimizing...

... ABSTRACT: The equation of Mohr-Coulomb salt dilation criterion has been developed obtained from the triaxial compression and extension laboratory tests of bedded salt. Numerical stimulations of the natural gas storage caverns in bedded salt formation are carried out by FLAC3D to evaluate...

... in the vicinity of existing underground caverns, which have to be adequately considered in order to estimate the natural state of stress. 1 INTRODUCTION Release of the state of stress is often the most relevant action during the excavation of an underground work, and it can affect the location and orientation...

... ABSTRACT: Incoherent results of in-situ stress measurements and their implications in designing a crude oil storage caverns project are presented in this paper. Core-discing at depths corresponding to abnormally higher stress magnitude values were observed at the project site. It is brought...
