Abstract
Fissure density is an important evaluation indicator of the degree of fissure development for fissure soils, which is not easily measured by traditional methods. A new statistical method based on Visual Basic programming was proposed to calculate fissure density. The basic principle of this method is to convert colour pixels into black-white pixels based on brightness calculation, and then calculate the fissure density according to the proportion of black-white pixels. Through the above methods, the statistics of the fissure density and fissure area of shrinkage soil sample can be realized.
