A Limited Study of Effects of Soil Strength on Walking Speed,
Abstract
The purpose of this study was to establish a relation between soil strength and walking speed. Ten tests were conducted on fine-grained soil and a wide range of soil strengths with five walking participants in most tests. Best relations were developed between walking speed and depth of footprint versus soil strength in terms of cone index. Walking speeds ranged from 0 mph on a cone index of 6 to about 4 mph on a cone index of 11; average walking speed on pavement was 4.67 mph. Walking speed increased from 0 to about 4 mph for depths of 22 in. (immobilization) and 5 in., respectively. Between the 5- and 0-in. footprint depths, speed varied between 4.0 and 4.5 mph.
