Rock mass are naturally occurring construction materials which are subjected to in-situ stresses. In-situ stresses occur due to the weight of overburden and tectonic stresses. Prior knowledge of in-situ stresses is important before aligning the longitudinal structures in rock mass such as tunnels and...

This paper highlights the role of stress measurements and wedge analysis for optimisation of orientation for underground desilting chambers and power house complex of hydropower development in the Himalayas. In-situ stress measurement tests were conducted using hydraulic fracturing technique in vertical...

In-situ stress parameters of the rock mass are one of the vital inputs for the design of any large underground openings. In general, the in-situ stress magnitude and orientation are influenced by topography, and major geological structures like folds, faults and intrusions. These structures bring about...
