Reliability Analysis of the GEOSL2000 Soil Passability Prediction Model and its Implications for Military Use

Abstract: The objective of this study was to validate a geoprocess model devised to predict soil passability based on in-situ measurements of soil bearing capacity. The bearing capacity of the soils was gauged using a conical penetrometer, and the measured values were juxtaposed with the Vehicle Coin Index (VCI) value for typical vehicles deployed in the Czech Armed Forces. Field measurements were conducted across nine distinct locations over a span of several years. The measured values were compared with the modelled passability, which was in line with the actual meteorological conditions on the individual days of measurement. The results clearly indicate that the model, created for the needs of the Army of the Czech Republic, exhibits significant inaccuracies. In mo st instances, it considerably overestimates the real situation. The primary recommendation of the research is the implementation of major modifications or the development of a new geoprocess model.
