ZHANG Hui-ying, ZENG Jian-min. Improvement of matter-element extension model and its application to classification of expansive soils[J]. 2008, 29(6).DOI:
The paper points out that incidence function of matter-element extension model is not convenient to calculate
and mutual exclusion of indexes has not been solved; so it has an influence on applied range of matter element analysis method. By constructing a new interval incidence function
matter-element extension model has been improved.
and solved mutual exclusion of indexes. The method is convenient to calculate
and widen applied range of matter element analysis method. It has been applied to determine expansive scale of expansive soils; and its reasonableness and effectiveness have been proved.
