Soil Measurements Related to the Performance of Soil-Machine Systems

The necessity of incorporating soil measurements in the evaluation of the performance of any soil working machine is presented. Emphasis is given to approaches to design problems, primary soil forces pertinent to a soil-machine system, and types of soil failures that are operable in a soil-machine system. Examples from research studies are given to demonstrate the importance of considering the soil in the evaluation of the performance of soil-working machines.
