"  Believe me its quiet interesting if you want to learn . "

 We , have already discussed two aspect of Geo-technical Engineering today we are going to learn the third aspect of Geo-Technical Engineering i.e.


                 Rock Mechanics :


                       

What is Rock Mechanics ?




Rock Mechanics determines , 

                                           How a Particular rock reacts when it is put to the use by mankind for buildings,roads,bridges,dams,tunnels,and other civil engineering uses.

Rock Mechanics will also allow engineers to decide how to protect slopes , the proper technique to be used for tunneling , the strengths that can be expected from rock that functions as a ballast ( is a material used to provide stability ) for railway tracks or as base for roads . The strength of rock also plays a large part in aggregate used for concrete that makes up the most buildings being built nowadays .

                 Nature of Rock :



A common assumption when dealing with mechanical behaviour of solid is that they are :

• homogeneous
• continuous
• isotropic

However rocks are much more complex than this and their physical and mechanical properties varies with scale. As solid material, rocks is often :

• heterogeneous
• discontinuous
• anisotropic

Rock as a Engineering Material :

Rock as an Engineering Material will be used either :

   as a building material so the structure can made of rock 

   or a structure will be build on the rock 

   or a structure will build in the rock 

In context of mechanics , we must establish :

the properties of material

the pre-existing stress

and the most important how these factor relate to engineering objective.
