TESTS WITH RIGID WHEELS. TESTS IN FAT CLAY, 1958

Abstract

The results of tests conducted to study the performance of a towed rigid wheel in a fairly soft clay are presented. The wheel was 48 in. in diameter and 6 in. wide. Five tests were conducted, each consisting of several passes of the wheel traveling at a speed of 1 fps over a test lane in which pressure cells were buried. The strength of the soil varied over a fairly narrow range. Measurements were made of deviation in static load, sinkage, motion resistance, contact pressure, stresses within the soil, and soil strength (cone index). The measured stresses were greater than the stresses computed by means of elastic theory by a factor ranging from about one to four. Nevertheless, measured stresses appeared reasonable. Although the program was limited in scope, the results were encouraging; an it is recommended that this type program be continued, using rigid wheels of various sizes in softer soils in the hope that generally applicable wheel-soil relations can be developed.
