This course covers the processes equipment special conditions and issues encountered in the drilling and sampling of frozen soils. Drilling and sampling in frozen ground is somewhat similar to performing the same operations in rock. Based on documented observations experiences of drilling in a range of geotechnical materials are covered. For finer grained materials such as silt clay organic material and ice at a few degrees below freezing For coarser-grained frozen soils such as coarse sands and gravels drilling was reported to be similar to drilling in concrete. Likewise reports from drillers describe drilling in frozen sand as “much like drilling sandstone.” The principal decisions for drilling and sampling in frozen soils include the selection of suitable drilling equipment a method of advancing and stabilizing the borehole drilling fluid and a refrigeration unit to cool the drilling fluid and drill string to a temperature equivalent to or slightly less than the temperature of the in situ formation. This course is based on the US Corps of Engineers' Manual: Geotechnical Investigations Chapter F-9 Pub. # EM 1110-1-1804
