Stress induced stability
assessment of the
underground caverns for
Moglicë HPP, Albania
By Martin Flåten
Supervisor: Krishna Kanta Panthi
Background
Moglicë HPP is the upper and largest power plant of the Devoll Hydropower Project in Albania.
The powerhouse and transformer hall are going to be placed underground. This MSc thesis
is to focus on the overall optimization of the orientation and placing of the two caverns and
the spacing between them. In addition, detailed stability assessment of the underground
powerhouse and transformer caverns will be carried out.
The stability analysis will be assessed through empirical, analytical and numerical approaches.
Necessary information about the geology will be collected from existing literature, feasibility
reports and previously performed laboratory tests. To perform the numerical stability
analysis, the software Phase2 will be used. The MSc thesis will be carried out in cooperation
with Sweco Norge AS, with Bent Aagaard as co-supervisor.
