摘要:

A computer program was developed to calculate bulk density(BD), coefficient of linear extenslbility(COLE), linear extensibility(LE), and linear shrinkage(LS) in the presence or absence of coarse fragments (>2mm). When coarse fragments are present in a soil clod, COLE and linear extensibility calculations become more complex, requiring additional equations and correction factors. The calculation of linear shrinkage is not sensitive to coarse fragments, thus requiring a single equation. This BASIC computer language program is accommodating to various parameter imputs and correction factors for fast calculation of BD, COLE, LE and LS in soil clods with and without coarse fragments.
