Measurement and Calculation of Fissure Area and Density for Shrinkage Soil

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.
