| Abstract: |
The Palomino HPP, with an installed capacity of 80 MW, is under construction in the Central Mountains of the Dominican Republic. The geological investigations for the 13.53 km long headrace tunnel were highly restricted due to difficult access in the mountain areas, high tunnel overburden as well as precautionary environmental protections in the National Park José del Carmen Ramirez. With respect to the approximately 12.4 km long TBM drive an exploration programme was carried out during excavation, to detect fractured zones as well as the presence of pressurised groundwater in advance. |
