“…field, in situ values were about 3.5 times lower than the Young's modulus needed to match modeled soil deformation to experimental data using a linear elastic Parker et al's (2009). values are in better agreement withYang et al (2015).…”

“…The measured values are lower than the calculated ones. Parker et al (2009) found that the measured Using uniaxial compression testing of frozen cores at high strain rate (10 %/s), Shoop et al (2005) report moduli values of 364 to 487 MPa for frozen fine sand (Lebanon Sand, SM) with volumetric ice content ranging from 17.6 to 21.9 %. These values are much closer to those predicted using equation [4].…”

More recent efforts Shoop 2009, Parker et al 2009) looked at stresses and deflections of heavy vehicles on compacted and frozen sands, silts, and clays, where the current NRMM approach is too conservative.

In the North Atlantic Treaty Organization Reference Mobility Model, the bearing capacity of frozen soils is a function of vehicle weight and frozen layer thickness. This relationship is based on the failure criteria of elastic plates extended to vehicle bearing capacity of ice sheets. In practice, this is found to be very conservative. A new study to investigate different approaches is underway. As part of this study, we examine how inherent soil physical properties change as a function of ice content, temperature, and engineering soil type. The final step will be to determine how these parameterizations affect the different bearing capacity formulations and to compare them to field data.

“…For non-peat soils, regardless of organic content, NRMM assumes that a frozen layer thickness of 5 cm is capable of supporting a vehicle of any size (Richmond 1991). More recent efforts studying the impact of vehicle-induced stress and displacement on frozen silt, sand, and clay (Parker et al 2009, Coutermarsh and have found that the current NRMM approach is too conservative.…”

In this report, we begin by investigating the different methods for calculating the seasonal bearing capacity of soils, including highly organic ones such as peat. First, we present the generalized plate theories, including failure criteria, for linear elastic, plastic, and modified plastic. In all instances, the plate is assumed to be uniform, circular, and of infinite extent. The physical properties that determine soil strength change with temperature, water content, and ice content. It is therefore important to accurately predict these. Therefore, we include a section on calculating the soil thermal conductivity, which determines the flow of heat. Following the discussion on thermal conductivity, we examine existing approaches and their appropriateness to our investigation. Finally, the end of the report discusses the need for better mobility predictions in regions where seasonality is important and highly organic soils are prevalent. As part of this, we note omissions and short falls in current methods and outline how best to correct these using a combination of theory, laboratory work, and field tests.
