In Thunder Bay, Ontario, a 2.16 m diameter tunnel is nearing completion in a soft to firm clay using a full-face tunnel boring machine and an unbolted precast segmented concrete lining. The lining consists of rings composed of four trapezoidal sectio

Performance of some structures constructed in rocks in southern Ontario have shown severe distress. It has been hypothesized that the problem is due to the high horizontal stresses existing in the rock formations. As part of a comprehensive investiga

A high-efficiency ground heat exchanger has been developed for use with ground-source heat pumps. The exchanger is made of copper tubing, shaped in the form of a spiral, which can be installed in a vertical borehole backfilled with sand. Thermal perf

Two methods of laboratory measurements of time-dependent deformations of rocks due to the relief of in situ stresses are described. Experiments were performed on specimens taken from seven rock formations in southern Ontario. It was found that some r

Most in-ground heat storage installations use a system of horizontal or vertical plastic pipes to carry heat exchanger fluid. In designing these systems it is generally assumed that the thermal effects of the plastic pipe can be neglected. This paper
