A comparison of uniaxial and borehole jack tests at Fort Providence Ice Crossing, 1995
A field test program was conducted on the ice bridge crossing near Fort Providence, N. W. T. during March, 1995. Cores of ice were extracted and tested on a portable test frame in uniaxial compression at a strain-rate of 2 x 10-3s-1. The ice temperature varied from -6 to -15º C over the course of th...
