Methods applied for the stability assessment in rock engineering

چکیده
The rock mass is exposed to stress changes after the excavation made for construction of infrastructures such as roads, railways, hydropower and irrigation projects. expansion roads requires slope cuts which cause natural discontinuities daylight leading failure different types magnitudes. tunnels underground caverns infrastructure projects will pass through with varying cover stability challenges. in in-situ condition therefore have direct impact on This key-note lecture highlight methods used make a assessment slopes excavations. focus be given most important aspect design covering failures, block falls issues associated conditions elastic brittle plastic material. Tunnels located shallow overburden are subjected de-stresses causing falls. On other hand, deep into (high cover) subject instabilities caused by induced stresses. If relatively unjointed massive, instability called spalling/ bursting. if weak deformable, deformation squeezing. Therefore, engineering challenging task needs knowledge behavior issue geologists engineers.

Probabilistic design: The future of rock engineering
A brief background to the development of the rock engineering design process is given, showing that since the development of the science of mathematics, deterministic methods have been used to perform various calculations. The variability of rock properties and support characteristics have always been known. However, they were not explicitly used in design but compensated for by the use of a sa...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
