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 and horizontal holes. Wedge analysis of the existing joint sets was also done to study the potential wedge failure and to optimize the orientation of underground caverns. The orientations of joint sets at outcrop were different than inside the cavern due to folding and faulting in rock mass. The final decision on orientation of large underground caverns was optimised based on in-situ stress measurements and analysis of existing joint sets inside the cavern. Keywords—hydrofracturing, wedge analysis, stereo plotting, isotropic stress theory
