INTRODUCTION Overview Himachal Pradesh, situated in the western Himalayas, is a beautiful mountainous state with constantly changing climate and a rugged topography (Kundu et al. 2017). Almost every year...

... Abstract Monitoring plays major role in every stage of the project from exploration, construction and operation of the underground cavern. Large cavern in Bhutan Himalayas is being monitored with geotechnical instruments since the construction period. The behavior of the cavern is being...

... Abstract This paper describes the formation of a large cavity in an underground complex at a hydropower plant in the Himalayas. The geometry of the cavity is controlled by the rock joints and foliation that intersected a major steeply dipping shear zone. For stabilization of the cavity, three...

The tunnel runs from Panjal Volcanics, a competent basaltic rock in which the power station is located, through a thrust zone, ending in red shale at the outlet side. At the Upstream end of the tailrace tunnel, after about 30 m...

The design of the powerhouse cavities is highly empirical and cannot be based solely on geological and petrographic description of rocks and on the past experiences particularly in rocks as prevailing in the Himalayas. The theoritical analysis of rock mechanics...

Ignorance of complete stress condition was one of the prime factors of failure. Experience of the authors in measurement of in-situ...
