Coupled Hydro-Mechanical Analysis of Excavation Damaged Zones around an Underground Opening in Sedimentary Rock

H. Abdi[1], E. Evgin[1], M. Fall[1], T.S. Nguyen[2], and G. Su[2]
[1]University of Ottawa, Ottawa, ON, Canada
[2]Canadian Nuclear Safety Commission, Ottawa, ON, Canada

A large amount of research work has been carried out in many countries to determine the viability of radioactive waste disposal in deep geological repositories. It is well known that excavation can cause damage around underground openings. On the other hand, the mechanical damage can ... Read More

Modeling Horizontal Ground Heat Exchangers in Geothermal Heat Pump Systems

A. Chiasson
University of Dayton, Dayton, OH, USA

Geothermal heat pumps use the earth as a heat source and sink via a ground heat exchanger (GHX) that consists of a network of buried heat exchange pipes, which can either be installed in vertical boreholes or in shallow horizontal trenches or excavations. The main goal in GHX design is ... Read More
