Would be reliable computing a finite element analysis of a dam-foundation system, using the rock mass parameters obtained through the GSI system, in order to evaluate the displacements in the rock mass, if you are using a software that not allow include information about the characteristics of discontinuities, only the rock mass stiffness?
Mr. Konstantinos,
If you know the characteristics of discontinuities in addition to the material properties then it is better to use rock joint model that includes discontinuities. If you use the software without simulate the characteristics of discontinuities then the results may not be correct. Because, the response of rock mass with discontinuities is different then the response of rock without discontinuities. In PLAXIS software rock discontinuities can be incorporated in the model and literature are available related to your problem..ok all the best in your research..
No certainly it is not reliable, rock discontinuities is a major item in determine both structural and seepage behavior of rock mass. if you don't have a detailed geological study, you may use geological maps to get the main faults locations and widths and from the RMR ( you may assume the worst for safety) you can estimate the width and spacing of minor discontinuities.
The foundation should be measured by calculating the beam
also the beam calculation analysis should be considered as claim
