Simulation of compaction by equipment in overburden replacement operations.

A combined stress-strain model for predicting soil compaction due to wheel traffic was developed based on a method for predicting stress distribution with the soil, as well as the development of a log- linear relationship between porosity, applied stress, and moisture content. A computer model that simulates equipment traffic patterns during overburden replacement operations utilized the combined stress-strain model to predict overburden compaction. Model predictions were compared with measured overburden densities determined by field measurements in a study of large surface mines in the midwestern United States that were originally characterized as prime farmland. Simulated levels of bulk density in subsoil and topsoil materials were in relatively good agreement with the field measurements, which corresponded to a variety of soil types, equipment types, and vehicle generation patterns.
