The porosity of coarse-grained soils relates closely other phsical mechanical parameters. On the basis of summarizing and analysing a great number of previous testing data
this paper plays a stress on the porosity of coarse-grained soils to study its correlatability with other physico-mechanical parameters using such methods as graphic representation
calculation and analysis and finally finds that there exists a positive or negative correlativity between the porosity and other indexe. To know this correlatability is clearly of paramount signifcane to controlling porosity effectively
analysing and pvedicting test parameters and rational selection of the parameters for researchers
