Laboratory tests were performed on 54 large size specimens of jointed rock mass under uniaxial loading conditions. Based on this experimental study, a methodology has been suggested to estimate strength and tangent modulus of rock masses through a weakness coefficient. The methodology involves mapping of joints in the field and laboratory testing of intact rock specimens to arrive at rock mass ...

The wireless devices that will soon be part of our day-today lives, and that may be the focus of our attention in our occupation today, will become more complex and more integrated into our lives. And there will be more to come. That the new devices will be more complex, both in the design phase and in the manufacturing test phase, is a certainty. History has shown this to be the case. As these...

ABSTRACT: A number of civil engineering projects which include river valley projects, transportation projects and metro rail projects are under construction in India. Various structures, such as underground openings, powerhouse caverns, metro tunnels, dam foundations and slopes are increasingly located in/on rock formations. The rock in its natural state is a very complex material especially wh...

the testing equipment and the methods of field tests used for calculating the modulus of deformation and elasticity of the shah _ abass dam foundation rock are described here. the communication includes conclusions of which a sharp difference between the quality of the roc kin the right and in the left bank is the most important.

Since rock fracture is a key property for different rock engineering applications, rock fracture measurement is often carried out in classifying the rock mass. Most geo-mechanics models (e.g. finite element) are of the equivalent continuum type in which fractures are represented not individually, but by their influence on a large element of the rock mass. Elastic modulus, for example, is obtain...
