CAGE/ASCE Joint December Meeting
NEPAL HYDRO PROJECT POST-EARTHQUAKE EVALUATION
Presented By: Ray E. Martin, Ph.D., P.E., D.GE
The Upper Tamakoshi Hydroelectric Project was under construction in 2015 when two large earthquakes occurred in Nepal. The presenter was part of a Panel of Experts1 (POE) assembled by the Upper Tamakoshi Hydropower Limited (UTKHPL), a subsidiary of Nepal Electricity Authority with the charge of evaluating: 1) differential settlements and displacements of various monoliths of the concrete dam under construction; 2) remedial measures proposed by project consultants for needed repairs; and 3) other critical issues observed that posed risks to the future completed project. These earthquakes adversely impacted the $441 million (U.S.) project including a cumulative vertical displacement of 7.5 inches which occurred between the right concrete dam abutment block and the adjacent concrete intake block and smaller displacements which occurred between the inlet culvert connected to the desanding basins and the outlet culvert connected to the power tunnel. There were also concerns about the competence of the left abutment and a 1000 ft high downstream landslide dam which supported the alluvium upon which a portion of the dam was founded. Because of the damage, the project construction was suspended and an assessment of the causes of the damage and other potential threats to the project moving forward were conducted.
