Quantitative description method & index for fissures in expansive soils
Yuan Jun-ping · Journal of Yangtze River Scientific Research Institute · 2003
The methods used for quantitatively observing expansive soils' fissures are summarized and evaluated. Dynamical and quantitative observations are carried out on fissure variations by longdistancemicroscopesystem. The results show that the gray level entropy of observed pictures can reflect the extent of fissures growth well and be suitable to use as an index to describe fissures in expansive soils.
