Additional Testing

Information on creep properties can be obtained from in-situ pressuremeter tests (Arenson et al., 2003; Ladanyi and Melouki, 1993). However, preboring is required, which may disturb the ground and influence the test results.

SPT (standard penetration testing) has been used in Arctic regions to measure the strength of the frozen ground. However, mechanical and thermal disturbances affect the ground and it is expected that the strength of the ground is higher than that ascribed empirically based on penetration rates. Cone penetration testing (CPT) in mountainous terrain is very problematic due to the coarse nature of most grounds. The probe is likely either be damaged or not to be able to penetrate the ground at all.
